Frontispiece: Mesoporous Silica Particles Integrated with All‐Inorganic CsPbBr₃ Perovskite Quantum‐Dot Nanocomposites (MP‐PQDs) with High Stability and Wide Color Gamut Used for Backlight Display

Dual-Protective CsPbX3 Perovskite Nanocomposites with Improved Stability for Upconverted Lasing and Backlight Displays

“…The formed color triangle regions are depicted in Figure d, where the optimal red and green emitters’ CIE coordinates are (0.7145, 0.2764) and (0.1512, 0.7728), respectively. Its gamut covers approximately 131% of NTSC space (Table S1), which is larger than those of Cd-QD LED (NTSC, 104%) and the traditionally designed phosphor-based LED display (NTSC, 86%) . More excitingly, the coverage of the color gamut can reach up to 97.7% of Rec.…”

“…A single core/shell structure of perovskite semiconductor quantum dots (QDs) was prepared by capping the CsPbBr 3 QD core with a CdS shell, which verified that the core/shell structure is capable of effectively enhancing the chemical stability of QDs. − Mixing green-emitting QD mesoporous SiO 2 composites with red-emitting PQDs is expected to address the issues of anion exchange and improve photoresistance and thermal resistance . Chemical doping has been proven to be an efficient way to solve the short-term durability problem. , However, none of these means could live up to the expectations and are still subjected to complex chemical processing steps.…”
