abstract = {Most of phosphors undergo thermal quenching (TQ) at high temperature, due to thermal-activated non-radiative transitions. TQ effects lead to significant reduced luminous efficiency of phosphors at high operation temperature, hindering their application in high power phosphor-converted white light-emitting diodes (WLED). Here, we report a zero-dimensional metal halide perovskite: Cs2ZrCl6:Sb3+, exhibiting robust anti-TQ red emission up to 500 K, comparable to the mainstream anti-TQ phosphors (e.g. K2SiF6:Mn4+). The hetero-valent doping of Sb3+ induces structure defects of host and thus compensate the non-radiative emission loss through thermal accelerated energy transfer from defects to emitter at high temperature. We assembled the red anti-TQ phosphor into a white light-emitting diode (WLED) device, achieving stable output light intensity and chromaticity up to 2000 mA.}
