Summary: Colloidal metal-halide perovskite nanocrystals have gained attention for their exciting properties and tunable emission range. However, they are limited by light-induced halide phase segregation. By controlling the thickness, monolayer nanoplatelets with narrow emission peaks and high radiative recombination can be synthesized, making them ideal for efficient LEDs.

Summary: This study demonstrates the use of methyl acetate (MeOAc) as an effective non-solvent for purifying MAPbBr3 PQDs without causing severe damage, facilitating stable PQDs solutions with high production yields. MeOAc-washed PQDs maintain high photoluminescence (PL) quantum yields and crystalline structures for long periods. Time-resolved PL analysis shows that MeOAc-washed PQDs exhibit suppressed non-radiative recombination and longer PL lifetime compared to acetone-washed and methanol-washed PQDs.

Summary: By introducing an interlayer between the electron-transporting and perovskite layers in perovskite solar cells, researchers have successfully enhanced charge extraction and transport from the perovskite, leading to higher power conversion efficiency and fewer interfacial defects. The coherent interlayer allowed the fabrication of devices with a certified efficiency of 25.5%, which maintained about 90% of its initial efficiency even after continuous light exposure for 500 hours. The findings provide guidelines for designing defect-minimizing interfaces in metal halide perovskites and electron-transporting layers.

Summary: Fluoride-treated CsPbBr3 nanocrystals exhibit near unity emission efficiency at temperatures up to 373 K, with constant decay kinetics. The treatment leads to surfaces rich in fluorine with wider energy gaps than the core, suppressing carrier trapping and improving thermal stability. Devices incorporating these nanocrystals show low turn-on voltage and high external quantum efficiency, with nearly 80% efficiency maintained at high temperatures, offering a promising pathway for high-performance light-emitting diodes based on perovskite nanostructures.

Summary: By using a hard-template solid-state synthesis at high temperature, highly stable CsPbBr3 nanocrystals with a high PLQY of up to 93% and a narrow emission linewidth of 18 nm are successfully prepared. The confined growth of nanocrystals in the thermally stable and uniform pores of the mesoporous silica template is the key factor for achieving high PLQY and narrow emission, while the pre-hydrolysis sealing strategy contributes to exceptional stability. Additionally, the emission intensity of CsPbBr3/MS@SiO2 is 3.8 times higher than that of commercialized silicate green phosphor when encapsulated on the blue-chip with the same absorbance at 450 nm, making it an ideal emitter for display applications.
