The crystallization of nano crystalline rare earth or alkaline earth fluorides is of high importance for optic applications. In this study, nano crystalline SrF2-Ge is precipitated. In contrast to recently studied glass-ceramic systems which allow the crystallization of alkaline earth fluorides, has used RF sputtering magnetron systems for creating SrF2-Ge crystallization. In a target with the mol% composition 3.7Al2O3/12.3SrO/5.3K2O/8.0Na2O/60.3SiO2/10.4SrF2 and Ge (3%, 5% and 10%).nano crystalline SrF2-Ge samples is formed in 6h, 8h, 10h, 12h, 14h and 16h after annealing the glass samples at temperatures in the range from 570 to 610°C for 3h. The XRD analyses show good crystallization structure for 16h samples. Absorption analyses showed increasing light scattering with increasing time of coating.The SEM analyses showed that size of nano crystals were between 50nm up 100nm and electric conductivity analyses show so big resistance for ceramic- glass crystals.
