Embedding Te(IV) into a Robust Sn(IV)-Based Metal Halide for Deep-Red Emission

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 14, 2025

Organic-inorganic hybrid Sn(IV)-based metal halides have received wide attention due to their excellent structural stability. However, realizing red-emitting with high stability and efficient photoluminescence (PL) efficiency remains challenging. Here, a stable organic-inorganic halide (C8H10O2N)2SnCl6 zero-dimensional (0D) structure has been obtained, which, however, displays poor PL properties the inert expression of Sn4+-4d10 electrons intrinsic indirect band gap feature. To address above challenges, Te4+ an active 5s2 lone pair is embedded into lattice (C8H10O2N)2SnCl6, as result, 5%Te4+-doped direct exhibits broadband deep-red emission (∼688 nm) (∼53%). Experimental calculated results reveal that embedding can effectively regulate facilitate transformation from structure, thereby leading radiative recombination. Benefiting merits, high-efficiency white light-emitting diode (WLED) fabricated using Te4+-doped ultrahigh color rendering index (CRI) up 94.5, suggesting great potential this material for solid-state lighting. This work provides significant insight design highly phosphors halides.
