Flexible, photoluminescent 0D Cs4PbX6 (X = Br, Br/I)-PMMA composite films for white LED via water-induced recrystallization
{{output}}
3D CsPbX3 inorganic perovskite materials have attracted much attention in optoelectronic devices because of their strong absorbance, high photoluminescent quantum yield, tunable band gap, and narrow emission bandwidth. However, their practical usefulness is li... ...
