Low-temperature crystallization of the K 2 TiF 6 :Mn 4+ phosphor with near-unity quantum efficiency in dilute HF solution
Abstract
Dilute-HF (≤30 wt%) + low- T cooling (20 → −40 °C) leads to the growth of mm-scale K 2 TiF 6 :Mn 4+ platelets with near-unity IQE and 10× better water resistance than powders, enabling 124 lm W −1 warm WLEDs.
