Perovskite Quantum Dots: CsPbBr3‐Quantum‐Dots/Polystyrene@Silica Hybrid Microsphere Structures with Significantly Improved Stability for White LEDs (Advanced Optical Materials 13/2019)
Source abstract
Abstract
In article number 1900546, Weizhen Liu, Haiyang Xu, and co-workers synthesize hybrid microspheres of CsPbBr3 perovskite quantum dots (PQDs) embedded in mesoporous polystyrene microspheres covered by a silica shell (CsPbBr3-PQDs/MPMs@SiO2), which exhibit high photoluminescence quantum yield of 84% and significantly enhanced stability, via a simple hydrolysis–encapsulation strategy. Enhanced chemical/physical stabilities make these CsPbX3 PQDs suitable for applications even in harsh environments. A phosphor-type white light-emitting diode has been fabricated based on these fluorescent microspheres, demonstrating a high power efficiency of 81 lm W−1 and good continuous working stability.
