摘要	The electro-optical characteristics of SrS:Ce and SrGa2S4:Ce as two kinds of hopeful blue TFEL phosphors have been intensively investigated. The color purity of SrGa2S4:Ce is better than that of SrS:Ce. In this paper, the influence of Ga3+ on photoluminescence (PL) characteristics of Ce3+ is first reported. Ga2S3 was doped into SrS, then sintered. The emission spectra shift obviously towards short wavelength range with increase of Ga3+ concentration. At the same time the relative intensity of the excitation peaks corresponding to the interband absorption of SrS reduces, and the excitation efficiency corresponding to the transition from the ground state to the excited state of Ce3+: ion increases. The ligand field around Ce3+ is changed by doped Ga3+. The ionicity of the substituted become stronger and Ce3+ - Ce3+ interaction become weaker. These are favorite to blue emission.
