Transparent oxyfluorosilicate glass-ceramics containing cubic SrF2 nanocrystals doped with Dy3+, Tb3+, and Dy3+/Tb3+ were successfully synthesized by melt quenching followed by heat treatment process. The crystalline phase of SrF2 nanocrystals during heat treatment was confirmed by X-ray diffraction: The emission intensity of glass-ceramics is much stronger than that of their parent glasses, on the one hand due to progressive incorporation of Dy3+ and Tb3+ ions within the SrF2 nanocrystals, on the other hand due to an efficient energy transfer from Dy3+ to Tb3+. Luminescence quantum efficiency of the samples was measured by using an integrating sphere. Luminescence decay curves of the F-4(9/2) level were fitted to Inokuti-Hirayama (IH) model for analyzing the energy transfer rates between Dy3+ and Tb3+ ions. The chromaticity coordinates were determined from the measured emission spectra and they are located at the green and white light regions. (C) 2016 Elsevier Ltd. All rights reserved.
