Highly luminescent lead halide perovskites such as MAPbX3 (MA = CH3NH3+, X = Cl, Br, I) have been synthesized from several research groups. To overcome their poor flexibility and stability, the perovskite nanocrystals embedded in a polymeric matrix have been investigated. Miscibility between polymeric materials and perovskite nanocrystals is an important issue to obtain high-quality composite films. The composite layers with perovskite nanocrystals embedded in polymeric matrix were successfully fabricated via in situ synthesis process. FAPbBr3-PVDF composite layers with different thickness were successfully prepared using in-situ fabrication method for the color converting layer. We demonstrate the two color white OLED display by using color-converting layer based on the organic–inorganic lead halide perovskites–polymer composites layer. Furthermore, we have fabricated color-converting layer with various perovskite nanocrystals to adjust the white emission in OLED display. |
