摘要：

Green phosphor compositions MgxSr1-xAl2O4:Eu, Nd (with x = 0.05-0.25) were prepared by solid state reaction method. The effect of Mg substitution on photoluminescence characteristics was investigated. The photoluminescence show intense green emission for MgSrAl2O4:Eu2+, Nd3+ with long persistence. This green emission corresponds to transitions from 4f(6)5d(1) to 4f(7) of Eu2+ ion. Comparative analysis of the excitation and emission spectra were used to evaluate the crystal field splitting of the 5d states of Eu2+ and the parameters of electron-vibrational interaction, such as Huang-Rhys factor, effective phonon energy, and zero-phonon line position.
