The cadmium silicate glass samples of 40SiO 2 -14Al 2 O 3 -(40-x) CdO-2Li 2 O-2K 2 O-2Na 2 O-xEr 2 O 3 (x=0.15, 0.20, 0.25, 0.30, 0.35, 0.40 mol) was prepared by high-temperature solid-state reaction method, and it is pumped at 488 nm, 532 nm and 800 nm respectively. The results indicate that the main peak wavelengths are at 547 nm, 731 nm and 1534 nm excited at 488 nm. The relationship of the intensity between the emission light of 731 nm and Er3 + -doped concentration is nonlinear. Near-infrared light nearby 1534 nm is excited at 532 nm and 800 nm, but it is weaker at 800 nm. The glass samples open a outlook of application for conversion luminescence materials.

The glass samples of SiO 2 -Al 2 O 3 -CdO-Li 2 O-K 2 O-Na 2 O with different Nd 3+ -doped concentration are prepared by high-temperature solid-state reaction method, and test the absorption spectrums as well as emission spectrum excited at 488 nm, 532 nm and 808 nm. The third-order optical nonlinear properties of glasses samples are investigated by the z-scan technique. With the increment of doping concentration of Nd 3+ , the third-order nonlinear refractive index and the absorption index increase, so it belongs to the self-focusing and reverse saturated absorption medium. The glass samples open a outlook of application for nonlinear optical medium and excellent luminescence materials.
