In this project, glass of composition 45GeO2-10Na20-10NaF-10ZnF2-25LaF3 was prepared. Optimization of fraction and size of LaF3 crystal was done by heat-treating the glassy matrix with fixed minimum amount of Er in the glassy matrix to maintain transparency of glass.The effect of heat treatment on solubility of rare earth ions in fluoride nano crystals will be examined. Based on this Er concentration will be optimized. To observe the effect of rare earth on crystallization, glass samples were examined under DSC to find the crystallization temperature. Phase identification was done by XRD analysis.
