Double perovskite Cs₂NaInCl₆ nanocrystals with intense dual-emission <i>via</i> self-trapped exciton-to-Tb³⁺ dopant energy transfer

Abstract

Tb 3+ ,Sb 3+ co-doped Cs 2 NaInCl 6 NCs with high PLQYs display dual-emission via energy transfer from self-trapped excitons to Tb 3+ . By further introducing Mn 2+ , the warm WLED device has been fabricated.
