Nucleation And Crystallisation Behaviour Of Transparent, Erbium Iii Doped, Oxyfluoride Glass Ceramics For Active Photonic Devices

A new Er3+ doped oxyfluoride glass ceramic composition is reported based on published compositions but with improved glass stability on reheating. A series of heat treatments up to 168h at 394 deg C, close to Tg (glass transformation temperature), has been carried out and yielded visually transparent materials. X-ray diffractometry has shown that a fluorite structured phase with lattice parameter 0.574nm has crystallised after the heat treatment.
