For weak light detection, phototransistors with high responsivity are needed. Furthermore, the ability to fabricate phototransistors using solution processing techniques will enable new form factors, including flexible and large-area devices. In this work, a novel approach for synthesizing a photosensitive organic/inorganic hybrid semiconducting thin film through solution processing is introduced. The approach involves hierarchical patterning of semiconducting carbon nanotubes (CNTs) with poly(3-hexylthiophene-2,5-dyl) (P3HT) through solution-phase heterogeneous crystallization. The fabricated hybrid phototransistors are qualified through electrical testing at varied illumination profiles within the visible light range. At a wavelength of 470 nm with an optical excitation power of 0.37 µW cm−2, the device exhibits photoresponsivity of 3.53 × 105 AW−1, surpassing other solution-processed, non-lead-containing devices in the literature. The optical response extends from both photogating (low excitation power) and photon-induced carrier generation (high excitation power). The detectivity of the device is ≈8.7 × 1010 Jones. The transient response includes a rise time of 100 ms and a fall time of 200 ms which is similar to the metrics of other low-dimensional photodetectors. These findings highlight the prospects of the solution-processed P3HT/semi-CNT hybrid platform for advanced photodetection applications with flexible and large-area form factors.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 30","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202401269","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142524697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although Mn doping in single-layer 2D hybrid perovskites (n = 1) has been extensively studied, limited research has been conducted on doping with modulation of the layer thickness. Herein, Mn2+ doping in hybrid 2D perovskite nanoplatelets (NPLs), L2An-1[Pb1-xMnx]nBr3n+1 (where L = butylammonium, A = methylammonium), with variations in Mn concentration (x = 0–0.60) and layer thickness (n = 1–3) is reported. Substitutional doping of Mn significantly increases the photoluminescence quantum yield as well as the rate of energy transfer efficiency, which strongly depends on the layer thickness of NPLs. The Mn concentration in 2D NPLs determines the rate of forward and backward energy transfer. Low-temperature emission spectra allow to determine thickness-dependent exciton binding energy for Mn-doped 2D NPLs (x = 0.5) with values of 410 ± 11 meV (n = 1), 188 ± 9 meV (n = 2), and 151 ± 17 meV (n = 3). The faster dissociation of band-edge excitons into free carriers at Mn2+ sites results in high brightness with an excellent CRI of 89.2 for the white light-emitting diode.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 31","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202401460","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, the terrible phase stability of CsPbI2Br film will cause a phase change in a wet environment and decelerate light response, seriously hindering the progression of IHP photovoltaics. Herein, a synergistic postmodification strategy with CsBr and MABr to achieve high-quality CsPbI2Br film at a low-temperature (≈150 °C) and positive perovskite/carbon interface is presented. Adding a small amount of MABr can promote the crystallization of perovskite. The evaporated CsBr accumulates on the grain boundaries and surface of CsPbI2Br and forms Br-rich perovskite, which provides the protection of CsPbI2Br and segregation of water vapor. The carbon-based perovskite solar cell (C-PeSC) with the modified CsPbI2Br harvests a high power conversion efficiency (PCE) of 11.04%. Notably, the unpackaged cell maintains 81% of its original PCE after being stored for 21 days in an air atmosphere with 25–35% humidity. Flexible devices are further manufactured, whose PCE drops to 90% of the initial value during 150 bending cycles. The flexible device also exhibits excellent blue photodetection performances. The maximum responsivity and detection reach 0.68 A W−1 and 8.91 × 1012 Jones, respectively. These findings provide broader avenues for flexible IHP in multifunctional devices.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 32","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642468","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 relationship between the structure and luminescence performance of 17 sulfonium salt derivatives confirms the pivotal roles of both the anions and the electronic and steric effect of substituent factors for luminescence. Single-crystal analysis reveals that unique ionic bonding and intermolecular interaction can promote an ordered arrangement of organic salts in a crystal state, which then can facilitate molecular aggregation for phosphorescence generation. Theoretical calculations have also confirmed this viewpoint. More importantly, these sulfonium salt derivatives can be used for advanced multimodal anti-counterfeiting and mitochondrial imaging, respectively.

This report is the first to demonstrate how the intrinsic difference in micropolarity drives the visualization of LDs in the green channel while ER in the red channel involves a single probe. The in situ emission spectra inside these organelles allow polarity quantification, further leading to deciphering the unique microenvironments in different cell lines. Exploiting ratiometric fluorescence imaging revealed how the micropolarity inside both LDs and ER alters during Ferroptosis.

However, they are highly defective when grown in ambient air due to the extremely poor air stability of Sn2+ ions in precursor solutions. It is discovered that the oxidation of Sn2+ to Sn4+ ions not only consumes Sn2+ ions but also increases the precursor solution viscosity. The increased viscosity slows down the solute diffusion and hinders the anisotropic growth of SCs, leading to Sn-Pb perovskite SCs with curved convex surfaces and unevenly distributed composition. By preventing the solute-diffusion-limited growth mode with hypophosphorous acid (H3PO2), high-quality Sn-Pb perovskite SCs can be robustly grown in ambient air with low trap density of 6.58 × 109 cm−3 and high carrier mobility-lifetime product (µτ) of 1.5 × 10−3 cm2 V−1.
