摘要：

In our paper, yttrium aluminum garnet doped with cerium (YAG:Ce) and terbium aluminum garnet doped with cerium (TAG:Ce) yellow garnet phosphors were prepared by a modified sol-gel method, using oxide, nitride as raw materials and acetylacetone, dimethyl sulfoxide, cetrimonium bromide in the hydrolysis and condensation step. The thermal treatment of the phosphors was performed at 1100 degrees C in order to transform it from amorphous to crystalline garnet phase. Structural, morphological, and luminescence properties were studied by Fourier transform infrared spectrometry, x-ray diffraction, scanning electron microscopy, and fluorescence spectroscopy. The results show that the modified sol-gel method provides a feasible approach to produce YAG:Ce and TAG:Ce yellow phosphors for the optoelectronic applications.
