All-inorganic lead halide perovskite nanocrystals applied in advanced display devices

“…[191][192][193] However, there is still a need to develop cost-effective and scalable manufacturing techniques for AILHP enhancement films. 194 As shown in Fig. 7c, organic semiconducting molecules were introduced as the capping ligands for stabilizing CsPbBr 3 QDEF films, which presented an extremely high stability in QD-enhanced LCD prototypes with harsh commercial accelerated operational tests.…”

A high-performance metal halide perovskite-based laser-driven display

“…1–5 As blue-to-green/red color converters that are sandwiched between a LCD's blue GaN backlight and traditional liquid-crystal module, MHPs are expected to outperform conventional phosphors (Mn- and Eu-containing oxides and fluorides) and commercialized quantum dots in the areas of color gamut, efficiency, and brightness. 6–8 Unfortunately, the existing MHPs only exhibit a high photoluminescence quantum yield (PLQY) with ultraviolet light (365 nm) excitation at room temperature (RT) which is closely related to the exciton local states formed by defects, and the PLQY is inferior under the excitation of blue light. 9,10 Moreover, the relaxation of surface ligands at high temperatures also yields larger PLQY deterioration with increasing temperature.…”

Ag Nanoparticles Optimized the Optical Properties and Stability of CsPbBrI2 Glass for High Quality Backlight Display

“…As the display industry continues to evolve, the market puts forward higher requirements on the performance of display devices. − All inorganic perovskite CsPbX 3 (X = Cl, Br, I) nanocrystal (NC) materials exhibit distinguished optical properties, including high carrier mobility, size-tunable emission, narrow full width at half-maximum (fwhm), − and high photoluminescence quantum yield (PLQY). , Over the past few years, they have been consistently identified as emerging frontiers, particularly in the area of backlight display applications, − generating significant interest among researchers. However, the instability of perovskite quantum dots (QDs), particularly their sensitivity to environmental conditions such as water, heat, light, and oxygen, significantly hinders their potential applications. − To keep pace with industrial development, it is imperative to optimize the performance and stability of perovskite QDs.…”
