摘要:Ni2+-doped SiO2, Al2O3-99SiO(2) glasses have been prepared by sol-gel method. The effect of Al3+ on the photoluminescence (PL) properties of Ni2+-doped SiO2 has been studied. Ni2+-doped sol-gel SiO2 glass shows an emission band at 510 nm, which is attributed to the d-d transition T-1(2)(D-1) --> (3)A(2)(F-3) of Ni2+ in octahedral sites. The emission of Ni2+ ions is greatly enhanced by the addition of Al3+ into SiO2. The study on Fourier transform infrared spectroscopy (FT-IR) and UV-Vis absorption spectra shows that the glass network and coordination environment of Ni2+ are changed after adding Al3+ into SiO2.
