Enhanced photoluminescence quantum efficiency of Cs <sub>3</sub> Cu <sub>2</sub> I <sub>5</sub> by modulating the superposition of exciton wavefunctions
The introduction of tetrabutylammonium (TBA + ) into zero-dimensional Cs 3 Cu 2 I 5 perovskite thin films increases the overlap of the exciton wavefunctions, resulting in superior photoluminescence properties and enhanced air stability.
