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.

While anticounterfeiting systems based on long persistent luminescence (LPL) materials demonstrate a mature trend, the integration of tunable luminescent lifetimes and emission colors in LPL-based remains challenge. Herein, we propose temporal spatial strategy utilizing novel zero dimensional (0D) metal halides, specifically (PBA)3BiCl6:xSb3+ (PBA = 4-Phenylbenzylamine, x 0, 0.05, 0.1, 0.15), which exhibit characteristics. A controllable color transition can be observed from green to white orange by varying excitation wavelength, accompanied different afterglow durations LPL emission. Additionally, various are at delay times. Furthermore, controlled duration is achieved through Sb3+ doping (PBA)3BiCl6, attributed triplet energy transfer (TET) process. noticeable when using mobile phone's flashlight as source, enhancing portability light source. The multifaceted tuning modulation establish foundation for multicolor time-resolved anticounterfeiting, significantly elevating security level advanced portable systems.
