With high transparency, high chemical stability, and mature fabrication, sol-gel glass is an ideal solid matrix to obtain such materials by chromophore doping. However, it remains a big challenge to obtain sol-gel glass with high luminous efficiency under a single excitation wavelength. Herein, the construction of highly luminescent sol-gel glass enabled by Förster resonance energy transfer (FRET) is reported. Branched siloxane is used to modify naphthalene and BODIPY, which led to the formation of blue-emitting donor (denoted as Si-Nap) and green-emitting acceptor (denoted as Si-BODIPY), respectively. Efficient FRET occurs between Si-Nap and Si-BODIPY proved by spectral titration and lifetime measurements, with an energy transfer efficiency (<i>Φ</i><sub>ET</sub>) up to 97.9%. When RhB is added, it acts as a final acceptor that enables the occurrence of a sequential FRET from Si-Nap to Si-BODIPY and further to RhB. The overall energy transfer efficiency reaches 94%, and the fluorescence quantum yield exceeds 88%. By adjustment of the composition, color-tunable sol-gel glass is obtained with emergence of white-emitting samples, opening potential applications in a variety of fields.</p>","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 2","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143112730","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}

This is owing to similar material properties of InP to those of commercial Cd-based QDs. Nonetheless, the surface quality of InP needs enhancement through a post-treatment process to eliminate surface oxides, typically with hydrofluoric acid (HF). The challenge arises with smaller, such as green InP QDs, as HF easily over-etch the InP cores, thus leading to an unpredictable size distribution and reduced production consistency. This research introduces a refined synthetic strategy that circumvents this over-etching phenomenon and offers a more precise control over the etching process of smaller InP QDs. By applying an additional protective layer to the InP cores prior to etching and employing ammonium fluoride (NH<sub>4</sub>F) as an alternative to the conventional HF, the over-etching incidence can be markedly mitigated.

A tunable optical high-order differential microscopy is proposed and implemented, in virtue of electric-driven liquid crystal (LC). By electrically switching the working state of LC, the differential operation can be flexibly tuned in desired order, such as from zero-order to first-order and second-order differentiations. Using this scheme, clear edge-enhanced images of different-contrast objects even transparent biological cells are experimentally acquired under multi-wavelength cases. Specifically, based on the connection between high-order differential results and edge features, further gained in-depth information in the size of light spot and structure of plant cells.

These substrates are thoroughly compared by replicating the upper surface of rose petals of different colors into a transparent polydimethylsiloxane (PDMS) mixture and subsequently sputtering Ag film of varying thicknesses. Ultimately, the white negative rose PDMS replica is chosen, demonstrating a high enhancement factor, good batch-to-batch reproducibility, high stability, and high sensitivity for crystal violet (CV), an organic contaminant with mutagenic and toxigenic properties. In a proof-of-concept experiment, the multiplex detection capability of this SERS substrate is demonstrated by analyzing a combination of two sets of analytes (CV and methylene blue as well as CV and Nile blue A).
