Thermal processing initiates the formation of barium bromide nanocrystals in the glass. Samarium enters the glass matrix either in its divalent or in its trivalent state. Fluorescence measurements indicate that during the annealing process Sm2+ ions enter the nanocrystals leading to enhanced fluorescence efficiency and to changes in the fluorescence lifetime.enfluorescencex-ray diffractionsamariumfluorozirconate glass ceramicbarium chloride nanocrystal621620530journal article
