| Abstract: | Liposomes are used as surface-capped ligands to modify the synthesized CsPbX3 nanocrystals. The capped CsPbX3 nanocrystals maintain their original shape and particle size, improve relative quantum yield by (100±3)%, and have adjustable emission spectrum in the range of 411-626 nm. It maintains cubic crystal form when stored in air(temperature 25℃, relative humidity 50%) for 150 d. The DOPC-CsPbBr3 NCs are used as a color converter to make white light-emitting diodes with a color rendering index of 91.2%, which has a broad application prospect. |
