Precursor Glass

Sm3+ doped transparent glass-ceramics of CaO-B2O3-SiO2 (CBS) system were prepared and characterized.The precursor glass was prepared by melting method and annealed at 450°C for 2h and cooled to room temperature at a speed of 5°C/min.The appropriate heat treatment schedule to precursor glass was determined to be 2h at 600°C for nucleation and 3h at 810°C for crystallizition.The transmittion of glass-ceramics at the range of visable light is 68% in average. Five main emission bands of Sm3+ are centered around 564nm,605nm,646nm,679nm and 789nm,which correspond to the 4G 5/2→6H 5/2,4G 5/2→6H 7/2,4G 5/2→6H 9/2,4G 5/2→6H 11/2 and 4G 5/2→6H 13/2 transitions.Very strong luminescence at around 599nm is observed in glass-ceramics,This indicates glass-ceramics to be a better host for Sm3+ than precursor glass and a hopeful laser material.

In this research, the effects of SrFe12O19: SF on optical and dielectric properties of Na2O-CaO-P2O5 glasses were investigated. From the study, the optically transparent glass, SF/Na2O-CaO-P2O5, system was successfully prepared by melt-quench method. The composition of SF/Na2O-CaO-P2O5 used in this study are ranging between 5-20 wt.% SF. It was found that the addition of SF enhanced the conductivity, but in turn reduced the percentage of transmittance in the glasses. The glasses subjected to be adding SF contents at higher than 15 wt% were opaque, while the lower range gave highly transparent glass ceramics. The dielectric constant (ɛr) of the SF/Na2O-CaO-P2O5 glasses were improved by increasing the content of SF, which in turn plays an important role in controlling the properties of the glass ceramics, including physical, optical, and dielectric properties.
