Although cesium halide lead (CsPbX3, X = Cl, Br, I) perovskite quantum dots (QDs) have excellent photovoltaic properties, their unstable characteristics are major limitations to application. Previous research has demonstrated that the core-shell structure can significantly improve stability of CsPbX3 QDs and form heterojunctions at interfaces, enabling multifunctionalization materials. In this article, we propose a convenient method construct core-shell-structured materials, in which...
In the realm of surface-enhanced Raman scattering (SERS) research, precise detection and effective cleansing substances are critical. This study introduces a novel Au nanotriangle/Cs2AgBiBr6 (Au NT/CABB) SERS array, synthesized through meticulous two-step process, which demonstrates remarkable effectiveness. Using Rhodamine 6G (R6G) as probe molecule, this substrate accurately detects target molecules achieves an exceptional threshold 1 × 10–13 M. The integration CABB into endows it with...
Long lifetime multicolor phosphorescence materials possess excellent optical properties and have important application prospects in the fields of advanced anti-counterfeiting information encryption. However, realizing long color-tunable room...
Room temperature phosphorescent (RTP) carbon dot (CD) materials have been widely used in various fields, but it is difficult to achieve a long lifetime, high stability and easy synthesis. In particular, realizing the phosphorescence emission of CDs using metal oxide (MO) matrix challenge. Here, solid gels are synthesized via situ hydrolysis, then RTP based on SiO2 (CDs@SiO2) hybridized with MO (CDs@SiO2-MO) by high-temperature calcination. Among synthesized, Al2O3 (CDs@SiO2-Al2O3) lifetime...
Lead-free double perovskites (DP) have the potential to become a rising star in next generation of lighting markets by addressing toxicity and instability issues associated with traditional lead-based perovskites. However, high concentrations hydrochloric acid (HCl) were often employed as solvent preparation most DPs, accompanied slow crystallization at temperatures, which not only raised risk cost process, but also had threat environment. Here, an situ fabrication strategy was proposed...
The inherent single narrow emission peak and fast anion exchange process of cesium lead halide perovskite CsPbX3 (X = Cl, Br, I) nanocrystals severely limited its application in white light-emitting diodes. Previous studies have shown that composite structures can passivate surface defects NCs improve the stability materials, but complex post-treatment processes commonly to dissolution NCs. In this study, CsPb(Cl/Br)3 was in-situ grown TiO2 hollow shells doped with Eu3+ ions by a modified...
The core-shell structure is an effective means to improve the stability and optoelectronic properties of cesium lead halide (CsPbX3 (X = Cl, Br, I)) perovskite quantum dots (QDs). However, confined by ionic radius differences, developing a packaging strategy suitable for entire CsPbX3 system remains challenge. In this study, we introduce optimized hot-injection method epitaxial growth CsPb2X5 substrate on surfaces, achieved precisely controlling reaction time ratio precursors. synthesized...
CsPbX3 (X=Br, Cl, and I) perovskite quantum dots (QDs) have become promising materials for phosphors solar cells due to their remarkable photovoltaic properties. However, the high defect density sensitivity surrounding environment hindered commercial application of in field optoelectronics. Core-shell structures been proved be an effective method passivating surface defects improving stability. complex post-processing tends dissolve QDs, causing strategy remain relatively underdeveloped....
