Abstract(summary):

During the investigation of concentration dependent properties of phosphors, such as emission intensities, the knowledge of the activator ion concentration is of great importance. Herein we present a study on recovery rate and homogeneity of the activator ion concentration by chemical analysis in luminescent europium doped metal hydrides. The analysis method was established on the model system EuxSr1-xH2 and applied to brightly emitting hydridic perovskites LiMH3:Eu2+ and LiMD3:Eu2+ (M = Sr, Ba). The nominal activator ion concentrations calculated from initial weights are in good agreement with those determined via ICP-MS for 10(-3)% <= x both for the hydrides (deuterides) and the parent alloys. The synthesis protocol thus allows a reliable method for reproducibly doping europium into metal hydrides. Luminescence spectra of LiEuxSr1-xH3 with x = 0.0037% show a broad band emission at room temperature typical for Eu2+ 4f(6)5d(1)-4f(7) transitions. Below 80 K, a vibronic fine structure is observed with vibrational coupling frequencies of approximately 100, 370 and 970 cm(-1).
