However, while most perovskite nanocrystals shine at green and red wavelengths, the observation of intense and stable blue emission still remains a challenging target. In this work, a method is reported to attain intense and enduring blue emission (470–480 nm), with a photoluminescence quantum yield (PLQY) of 40%, originating from very small CsPbBr3 nanocrystals (diameter < 3 nm) formed by controllably exposing Cs4PbBr6 to humidity. This process is mediated by the void network of a mesoporous transparent scaffold in which the zero-dimensional Cs4PbBr6 lattice is embedded, which allows the fine control over water adsorption and condensation that determines the optimization of the synthetic procedure and, eventually, the nanocrystal size. The approach provides a means to attain highly efficient transparent and stable blue light-emitting films that complete the palette offered by perovskite nanocrystals for lighting and display applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 32","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202400763","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642296","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}

To validate this hypothesis, a photo-induced current is measured in SRN thin films with refractive indices varying between 2.5 and 3.15 when a C-band laser light is illuminating the SRN films at various powers, indicating the generation of free carriers. Furthermore, nonlinear loss dynamics is, for the first time, measured and characterized in detail in SRN waveguides by utilizing high peak power C-band complex shape optical pulses for estimation of free carrier generation (FCG) and free carrier recombination (FCR) lifetimes and their dynamics. Both FCG and FCR are found to decrease with an increase in the refractive index of SRN, and, specifically, the FCR lifetimes are found (92 ± 7) ns, (39 ± 3) ns, and (31 ± 2) ns for the SRN indices of 2.7, 3, and 3.15, respectively. Lastly, nonlinear losses in high refractive index SRN waveguides are demonstrated to be minimized and altogether avoided when the pulse duration reduced below the free carrier generation lifetime, thus providing a way of taking a full advantage of the large inherent SRN nonlinear properties.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 32","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202401299","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642109","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}

Herein, the core/shell heterostructural variation of blue-emitting ternary ZnSeTe QDs by manipulating ZnSeTe core size (small versus large) and ZnSe inner shell thickness (thin versus thick), while ZnS outer shell thickness remains unaltered, is explored. EL outcomes of the resulting core/shell QDs having photoluminescence quantum yields of 59−80% within the blue color regime (454−463 nm) are found to be dependent on their heterostructural dimension, exhibiting the highest performances of 31709 cd m−2 in luminance and 11.4% in external quantum efficiency (EQE) from large-ZnSeTe/thick-ZnSe/ZnS QDs. Furthermore, to address the chronic issues of excessive electron injection and exciton quenching at emitting layer/electron transport layer (ETL) interface, the surface of ZnMgO (ZMO) nanoparticle (NP) is modified by bicarbonate functional species. Bicarbonate passivation not only leads to the effective reduction of defective sites on the ZMO NP surface toward the suppression of exciton quenching but induces the upshift of ETL band alignment in favor of charge balance. As a result, the optimized blue device incorporated with bicarbonate-functionalized ZMO NPs delivers a peak luminance of 39739 cd m−2 and a maximum EQE of 17.1%.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 32","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142641885","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}
