In the range of experimental concentrations (≤4 mol%),luminescent intensities of Eu￣(3+)and Tb￣(3+) increase as their concentrations increase,the concentration quenching of Sm￣(3+)and Dy￣(3+) luminescences is able to be observed,and no large concentration quenching can be observed in Ce￣(3+) doped glasses,Various mechanisms of concentration effects of rare earth ions are analysed.
