| Abstract: | According to the Van Uitert experimental equation, crystal-lattice environment of Eu2+ in the Sr4Si3O8Cl4 crystal was discussed. By adding Mg2+ to the host lattice, Sr4-xMgxSi3O8Cl4∶Eu2+ was synthesized and the emission peak shifted from blue-green (488 nm) to blue-violet (411 nm) with the increase of amount of the magnesium which replaced the strontium. By analyzing the spectra of Sr4-xMgxSi3O8Cl4∶Eu2+ the two Eu2+ 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. |
