Tailored efficient energy transfer Tb³⁺, Eu³⁺activated/co-activated LiAl(PO₃)₄phosphor by substitution of alkali metals: the effect of charge compensation

Abstract

The studied phosphor LiAl(PO3)4: x mol% Tb3+, y mol% Eu3+, z mol% R+ (R = Na, K) shows excellent photoluminescence properties with efficient energy transfer from Tb3+ to Eu3+, enhancement in intensity using charge compensation and show the photochromic nature.
