The emission spectrum shows a single intensive band centered at 475nm, which corresponds to the 4f65d1→4f7 transitions of Eu2+. The excitation spectrum is a broad band extending from 250 to 450nm, which matches the emission of ultraviolet light-emitting diodes (UV-LEDs). The effect of doped Eu2+ concentration on the emission intensity of Sr2ZnSi2O7: Eu2+ was also investigated and the corresponding concentration quenching mechanism is verified to be an electric multipole-multipole interaction.
