共沉淀法制备Gd3（In,Al）5 O12∶Ce石榴石粉体
Preparation of Gd3 (In,Al) 5 O12∶Ce Garnet Powder by Co-precipitation Method
摘要
Abstract
The solution containing Cd3+ In3+, Al3+ and Ce3+ was acquired by dissolving the reagents of Gd2O3、In2O3、NH4Al(SO4)2·12H2O and Ce2(CO3)3 in diluted nitric acid. The precursor of sulfate carbonate basic hydrate was synthesised by means of co-precipitation method. GIAG∶Ce garnet powder with cubic crystallic system was prepared by sintering the precursor at the temperature above 950℃. The characteristic functional group and thermal chemical behavior of the precursor was investigated by infrared spectrum and differential thermal analysis. The phase transformation of the precursor samples subjected with the sintering treatment under the different temperatures was analysised by X-ray powder diffraction. The SEM images and grain size distribution of GIAG∶Ce powder was characterized by surface electron microscope and grain size analysis. The Fluorescence spectra of GIAG∶ Ce powder exhibites two luminescence peaks at the wavelength of 365 nm and 450 nm, which proved that Ce3+ ions has been doped into the crystalline lattice of garnet powder.关键词
