Organic–inorganic lead halide perovskites materials have been attracted as important materials for various optoelectronic applications. To overcome their poor flexibility and stability, the perovskite nanocrystals embedded in a polymeric matrix have been investigated. The composite layers with perovskite nanocrystals embedded in polymeric matrix were successfully fabricated via in situ synthesis process. Perovskite-PVDF composite layers with different thickness were successfully fabricated using the color converting layer for the two-color white OLEDs. We demonstrate efficient white OLED display by using color-converting layer based on the organic–inorganic lead halide perovskites–polymer composites layer. Consequently, we have fabricated color-converting layer with various perovskite nanocrystals to adjust the white emission in OLED display.
