Abstract：Europium doped SrSiO3 was synthesized by the hydrothermal method in a stainless-steel autoclave. The crystal structure, shape and size of the product were analyzed by X-ray Diffraction and Transmission Electron Microscopy. The reactions of the crystals SrSiO3 during the hydrothermal process were discussed based on the result of XRD patterns. The photoluminescence properties of Europium doped SrSiO3 annealed at different temperatures were measured using FL-4500 Fluorescence Spectrophotometer with a Xe lamp source. Only one red emission peak with the wavelength at 596nm was observed in the hydrothermal products without any heat treatment When samples were annealed in air at 800℃, wavelength of the red emission shifts to 604nm, and the intensity of the red emission is enhanced greatly. When the samples were treated in H2 ambience, a wide band with the wavelength at 460nm appeared with the excitation bands at 268nm and 355nm. The intensity of this band increased with the increasing of the heat treatment temperature.
