Highly-stable and homogenous perovskite-based luminescent films with honeycomb-patterned surfaces

Abstract

Here, we report the formation of highly-stable and homogenous perovskite-based luminescent films with honeycomb-patterned surfaces by using the breath-figure method. The optimized PGPO@CsPbBr₃ film exhibited uniform honeycomb-patterned pores that endowed it with uniform luminescence, high stability, and hydrophobicity. This work provides a new approach for fabricating highly-stable and homogenous perovskite-based luminescent films for full-color backlight displays.
