Abstract：A new europium strontium oxide was synthesized by high-temperature solid state reaction of SrCO3 with Eu2O3 in air. The new multiple oxide was characterized by use of XRD, TG/DTA and fluorescence spectra. The XRD results show that the molecular formula of the europium strontium oxide is SrEu2O4, whose structure is isostructural with that of BaEu2O4 reported earlier. The excitation spectrum of SrEu2O4 displays a broad double peaks band with one peak around 257 nm and the other around 280 nm. This broad band is attributed to the charge transfer transition of Eu3+—O2- bonds. Excited with a radiation of 280 nm, SrEu2O4 emits strong red light which is assigned to the 5D0→7F2 electric dipole transition of Eu3+.
