Raman and x-ray diffraction study on the material property of oxyfluoride vitroceramics

Upconversion study is imperative now to find good material that has high laser damage threshold, good physics and chemical property, easy in processing in order to develop various up- conversion applications. This paper studies the material property of oxyfluoride vitroceramics by Raman and x-ray diffraction spectroscopy. It reveals the physical reason why the Er3+ ion's upconversion luminescence in oxyfluoride vitroceramics is 101 times greater than that in oxyfluoride glass.
