Effect of SiO2 on Red Luminescent Materials Eu3+∶ZnO1-xSx
The ZnO1-xSx-SiO2 doped Eu3+ luminescent materials were prepared by sol-gel-precipitation method. The luminescence properties and structure of the materials were studied by IR, XRD, TEM, EDS and excitation spectroscopy, emission spectroscopy, and the focus of the research is the effect of SiO2 incorporation on the luminescence properties of luminescent materials. The results show that the samples have formed the chemical bond of Si-O-Si, Zn-S and Si-O4 perssad, introduction of SiO2 can improve the luminescent properties of the materials. And determine the optimum annealing temperature is 800 ℃, the content of S is 2.4at%, the optimum excitation wavelength of the material is 395 nm. Finally, the mechanism of material luminescence is presumed based on the structure.
