英文摘要Er3+ doped srf2-sio2 transparent glass ceramics were prepared by sol-gel method and heat treatment. the decomposition of sr2+-cf3coo- and the formation of srf2 nano-crystals were found to proceed synchronously in the xerogel. after crystallization of the xerogel, srf2 nano-crystals with 8-10 nm in size distributed homogenously among the glassy matrix, and the microstructure of the glass ceramic was stable under and at the temperature of 800 degrees c probably due to interfacial interaction between nano-crystals and glassy matrix. when heat-treated at 800 degrees c, the chemically bonded water in the sample was eliminated, resulting in the appearance of the visible luminescence bands of h-2(11/2) (4)s(3/)2 -> i-4(15/2) and f-4(9/2) -> i-4(15/2) transitions.
