摘　　要：报道了在室温和液氮温度下分别用1064nm和532nm激光诱导的Cr:Mg_2SiO_4晶体的红外光致发光谱,并详细分析光谱的结构和特点.在假设Cr:Mg_2SiO_4晶体中同时存在(CrO_6)^(9-)和(CrO_4)^(4-)两种络离子的基础上讨论了红外光致发光的产生机理,理论计算证明假设是合理的.The laser induced infrared fluorescence spectra of the crystal Cr:Mg_2SiO_4 at room temperature and liquid-nitrogen temperature with the wavelength of inducing laser being 1064and 532nm, respectively, are reported. The characteristics of the infrared fluorescence spectra are described and analyzed. On the assumption which is verified by theoretical calculations that the complex ions (CrO_6)^(9-)and (CrO_4)^(4-)simultaneously exist in the crystal Cr:Mg_2SiO_4, the interpretation of infrared fluorescence spectra is discussed.
