| 摘 要： | According to the Van Uitert experimental equation, crystal-lattice environment of Eu^2 in the Sr4Si3O8C14 crystal was discussed. By adding Mg^2 to the host lattice, Sr4-xMgxSi3O8C14:Eu^2 was synthesized and the emission peak shifted from blue-green (488nm) to blue-violet (411nm) with the increase of amount of the magnesium which replaced the strontium. By analyzing the spectra of Sr4-xMgxSi3O8C14:Eu^2 the two Eu^2 emission centers were found because of the change of crystal-lattice environment in the host and the crystal structure was obtained by X-ray diffraction data.
