    Abstract

    The transparent colored glass ceramics were obtained and based on the controlled nucleation and crystallization of Li 2O Al 2O 3 SiO 2 system glasses containing little TiO 2, ZrO 2 and P 2O 5 as nucleating agent and rare earth of transition metal ions as coloration agent. The temperature of nucleation and crystallization was determined with DTA analysis. The transmission of the obtained glass ceramics were measured and investigated in the range of ultraviolet to near infrared wavelength. The results show that the transmission of glass ceramic is reduced due to the scatter of micro crystallites for the light, while the instinct absorption peaks of rare earth in the host glass are almost the same as that after nucleation crystallization of the glass. The effects of glass and glass ceramics on the absorption spectra of rare earth and transition metal ions were discussed.
