Erbium- and chlorine-doped fluorozirconate-based glasses for up-converted fluorescence
Abstract
A series of glass ceramics was prepared and its structure-property relationships evaluated. The base composition of the series was comprised of fluorozirconate (FZ) and fluorochlorozirconate (FCZ) glass ceramics. Thermal processing of as-made FCZ-based glass ceramics produced sharp peaks in x-ray diffraction patterns, which was attributed to barium chloride nanocrystals formed in the material; this was not observed in the FZ glass. Up-conversion fluorescence experiments were carried out for both the FZ and FCZ samples doped with erbium. The fact that an increase in the up-conversion efficiency was not observed indicates that erbium ions were not embedded in the barium chloride nanocrystals. A comparison is made between this series and a similar series that was doped with neodymium.
