摘要：Micro-crystals of Bi4(GexSi1-x)3O12 (x = 0, 0.25, 0.5, 0.75, 1) solid solution series were synthesized by a sol-gel method, using stoichiometric Si(OC2H5)4, GeO2, Bi(NO3)3.5H2O as the starting materials. The as-prepared series were studied by X-ray diffraction, Raman spectra, differential thermal analysis, and fluorescence spectra. Experiments showed that single phase of Bi4(Si1-xGex)3O12 was obtained by the sol-gel method. For all the composition, Bi4Si3O12 and Bi4Ge3O12 can completely dissolve into each other. The refined cell parameters were in proportion to the composition. Bi4Ge3O12 showed the strongest fluorescence emission while Bi4Si3O12 showed the weakest fluorescence emission.
