However, the development of carbon dots-based phosphorescent materials that are excited by visible light and have adjustable colors remains a challenge. Here, we report on phosphorescent composites based on multicolored fluorescent carbon dots (CDs) and polyacrylamide (PAM) with four phosphorescent colors (blue, green, yellow and red). The phosphorescence of CDs@PAM composites is mainly derived from the C=O bonds of CDs. Electron transition of n-π* in the C=O bonds facilitates the intersystem crossover that are necessary to generate phosphorescence. In addition, the hydrogen bond actions between the amide groups of PAM polymer and the functional groups on CDs surface also promote the intersystem crossover and inhibit the non-radiative relaxation of triple states (T₁) in CDs@PAM. Meanwhile, the PAM matrix provides a rigid protective environment (hydrogen bond mesh structure) that inhibits vibrations, rotations and collisions of the CDs' luminescent clusters (C=O), avoiding the rapid decay of phosphorescence. Four kinds of CDs based phosphorescence materials can produce brilliant phosphorescence under the excitation of visible light (flashlight). Finally, their colorful phosphorescent colors were used to achieve a naked-eye observable anti-counterfeit pattern, demonstrating the potential application of these materials.</p>","PeriodicalId":48495,"journal":{"name":"Materials Today Advances","volume":"44 10","pages":""},"PeriodicalIF":10.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138525812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors present an innovative, easy-to-use and rapid process for producing ZrN thin films from a photo-structurable ZrO₂ sol-gel using a rapid thermal nitridation (RTN) process. In this process, a ZrO₂ sol-gel layer is converted into a ZrN thin film in a few minutes by rapid thermal annealing (RTA) under ammonia gas. Compared to physical or chemical vapor deposition, usually used to produce ZrN thin films, the advantages of the sol-gel method include suitability for non-planar and large substrates and the possibility of nanotexturing of crystallized ZrN surfaces in considerably less time, at a larger scale and at a lower cost. The ZrO₂ and ZrN thin films were characterized by Raman spectroscopy, X-ray diffraction and Transmission Electron Microscopy, to confirm complete nitridation. The optical, electrical and tribological properties were also investigated.

In this work, we report a rational strategy for synthesis of yellow fluorescent carbon nanodots (Y-CDs)-based microparticles with a high solid-state photoluminescence quantum yield (32.02%). It is the first report on designing a lamellar structured matrix to disperse CDs to realize long-wavelength solid fluorescence.

Meanwhile, through adjusting the amount of KH-560, the morphology of Y-CDs-based microparticles can be controlled from cube to layered structure and the fluorescence intensity can be significantly improved. Importantly, the optimal Y-CDs particles can be combined with blue chips (450 nm) to fabricate high-performance white light-emitting diodes (WLEDs) without using commercial phosphor, and the constructed WLEDs exhibit a high color rendering index (CRI) of 84.2.</p>","PeriodicalId":48495,"journal":{"name":"Materials Today Advances","volume":"11 3","pages":""},"PeriodicalIF":10.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138525760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For optimal performance in wearables, TENGs need specific characteristics like air permeability, durability, washability, and self-healing capability. In a novel approach, we utilized polybutadiene-based urethane (PBU), equipped with Diels-Alder networks, as a triboelectric material. This choice lends our design washability, self-healing capabilities, and considerable mechanical strength. PBU's abundant amine groups are key to enhancing its triboelectric properties, facilitating electron transfer between materials and contributing to high charge density. We also used polyvinylidene fluoride (PVDF) electrospun fibers as the negative layer, chosen for their electron-attracting ability and flexibility. These components were electrospun onto a conductive fabric coated with copper-nickel to optimize the contact area and increase wearability. Our device, measuring 2500 mm², generated approximately 113 V and a rectified current of around 8 μA at 0.98 kPa external pressure and a 5 Hz frequency. Impressively, it maintained performance despite thousands of wash cycles and various deformities, demonstrating unique self-healing abilities following severe surface damage. The TENG has demonstrated its real-world potential by powering up to 150 LEDs, efficiently operating calculators, thermometers, hygrometers, and even functioning as a warning device through normal walking motion. Moreover, its air permeability allows for electricity generation from the wearer's breath when attached to a regular mask, as evidenced by successful LED lighting by human normal breathing.</p>","PeriodicalId":48495,"journal":{"name":"Materials Today Advances","volume":"45 2","pages":""},"PeriodicalIF":10.0,"publicationDate":"2023-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138525766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Devices governed by pressure or strain sensors particularly demand such attributes. Responding to this technological imperative, our study endeavored to conceive an intelligent door security apparatus grounded on the universally adopted numerical input system. Despite the commercialization of identification systems such as fingerprint, iris, or facial recognition, these mechanisms suffer from susceptibility to a variety of functional aberrations. Consequently, our investigation concentrated on a security system predicated on numerical input. This necessitated the formulation of a swift, self-powered pressure sensor characterized by sensitivity to minute pressure changes. As such, we engineered a triboelectric pressure sensor incorporating a composite of Ti₃C₂-based MXene and polydimethylsiloxane (PDMS) as the electronegative stratum, and Nylon functioning as the electropositive layer. Addressing the sensor's intrinsic deficiency in sensitivity to pressure, we augmented the MXene-PDMS composite's surface with an out-of-plane wavy structure, and utilized a Nylon stratum composed of nanofibers, thereby amplifying the contact area under pressurized conditions. This meticulously developed sensor displayed a sensitivity metric of 0.604 kPa⁻¹ at 15 kPa, and notably, the swiftest response times recorded amongst triboelectric pressure sensors to date. Post attachment of the sensor to a numeric keypad (ranging from 0 to 9), we meticulously measured the signal alterations contingent on each key press, resulting in a comprehensive dataset. Employing a multitude of machine learning algorithms, we realized an exemplary degree of precision in both training and testing phases. The pragmatic implications of this work are noteworthy. Not only does our technology facilitate the unlocking of a door by entering the correct numerical code, but it is capable of recognizing distinct triboelectric signal patterns, corresponding to the specific manner of key entry by an authorized user, offering an additional dimension of security.</p>","PeriodicalId":48495,"journal":{"name":"Materials Today Advances","volume":"10 10","pages":""},"PeriodicalIF":10.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138525754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
