Abstract
We have synthesized three ZBLAN:Pr3+,Yb3+ glasses consisting of 53ZrF-20BaF2-4LaF3-3AlF3- 20NaF with different Pr3+:Yb3+ ratio, and characterized the quality of glasses with the optical and thermal parameters. The up-conversion in red, orange, green and blue in ZBLAN:Pr3+,Yb3+ (Pr3+:3000; 5500 ppm) glasses is observed under LD at 970 nm and Tungsten-halide lamp (200 W) at 883 nm excitation. And in ZBLAN:Pr3+,Yb3+ (Pr3+:8000 ppm) glass only the green up-conversion is obtained. We found that the wavelength at 883 nm is the optimum to obtain the blue up- conversion in both glass samples.
