Abstract

Abstract Europium-doped silicate Ca3MgSi2O8 has been successfully obtained using solid-state reaction at 1400 °C in a vacuum atmosphere. The photoluminescence study of Eu2+ in investigated host showed broad emission band with a maximum at 480 nm attributed to the allowed 5d → 4f electron transition of Eu2+ located in two different crystallographic sites. The excitation, emission spectra as well as the luminescence decays were analyzed. Thermal quenching process begins at 240 K, however, the emission stability of investigated compound is quite good, and emission intensity reached to 70% of its initial value at 100 °C. The QE of Ca3MgSi2O8: 0.5% Eu2+ excited at 365 nm equal to 47%.
