Enhanced deep-blue emission and quantum yield of Ca 0.995 YGaO 4 :0.5%Bi 3+ via lithium-based flux additives

Abstract
Bi 3+ -doped CaYGaO 4 phosphors were synthesized via solid-state reaction. Compared to Li 2 O, which suppressed PLQY to 55%, Li 2 CO 3 flux significantly optimizes the synthesis, enhancing blue PLQY from a pristine 58% to a superior 70%.
