Abstract
- Transparent glass-ceramics containing Er<superscript>3+</superscript>:CaF<subscript>2</subscript> crystallites were prepared with the co-firing method. The formation process of the glass-ceramics was investigated by means of SEM, XRD, and DSC. The results reveal that the Er<superscript>3+</superscript>:CaF<subscript>2</subscript> nanocrystals do not dissolve into the fluorophosphates ( FP) glassmelt until the co-firing temperature increase higher than about 920°C. Below this temperature, Er<superscript>3+</superscript>:CaF<subscript>2</subscript> survives the co-firing process and the nanocrystals just grow to spherical crystals of micrometers in size. Co-firing temperature higher than this temperature leads to the dissolution of Er<superscript>3+</superscript>:CaF<subscript>2</subscript> and the dissolved Er<superscript>3+</superscript>:CaF<subscript>2</subscript> recrystallized during quenching process and takes the shape of dendrite.
