摘 要：<正> The fluorescent characteristic and emission spectra of Eu2+ in the cubic structureCa8Zn（SiO4）4Cl2 with three kinds of cation sites is reported.The influence of temperature,Eu2+ concentra-tion and excitation conditions on fluorescent properties of Eu2+ are studied at 77 and 298 K.Thecoordination number of Eu2+ at different sites is obtained.The green and red emission bands arise fromEu2+ ions locating on eight- and six- coordinated inequivalent sites respectively.
