| Abstract: | Under various doping concentrations and co-doping with cerium ions(Ce~(3 )),terbium ions (Tb~(3 ))doped SiO_2 nanocomposites were prepared successfully by using a modified sol-gel method. Through the characterization of X-Ray diffraction and the examination of excitation and emission spectra,the photoluminescence properties of the samples are investigated under various doping concentrations and different anneal treatment temperatures.Some new and interesting photoluminescence properties of single Tb~(3 )doping and co-doping of Tb~(3 )and Ce_(3 )SiO_2 glass were discovered. |
