Efficient blue-light-excitable broadband cyan-emitting phosphors may yield full-visible-spectrum white light-emitting diodes (WLEDs) with ultrahigh color rendering (Ra > 95). However, this requires closing the "cyan gap" in 480–520 nm region of visible spectrum, which is challenging. Herein, a well-performed garnet phosphor Ca2LuAlGa2Si2O12:Ce3+ (CLAGSO:Ce3+) reported. Under 430 excitation, optimal CLAGSO:5%Ce3+ compound exhibits cyan emission (peak, 496 nm; bandwidth, 102 nm) high internal quantum efficiency 85.6% and an excellent thermal resistance performance (69.1% at 423 K). Importantly, as-prepared provides sufficient enables filling well-known so-called between blue LED chip commercial Y3Al5O12:Ce3+ (YAG:Ce3+) yellow phosphor. Impressively, WLED device fabricated sample shows low correlated temperature (4053 K) index = 96.6), as well luminous efficacy (74.09 lm W–1). These results highlight importance blue-excited gap enabling human-centric warm devices for high-quality solid-state lighting.

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.
