codoped oxyfluoride ceramic glass was prepared and their up-conversion luminescence property was studied under the pump of 980 nm diode laser. In the luminescence spectra of annealed samples
stark splits of luminescence were observed at 463 nm and 476 nm. Temperature property of this split was studied between 303 K and 623 K. The results indicate that Tm
