Yellow Up-Conversion Luminescence of Transparent Glass Ceramics with Erbium Ions

A transparent glass ceramic, containing lead fluoride β-PbF2 nanocrystals with erbium ions Er3+ (average diameter 8.5 nm), was synthesized by means of secondary thermal treatment of the initial oxyfluoride glass of the system SiO2–GeO2–PbO–PbF2, doped with Er2O3. Its thermal and structural properties, optical absorption, and up-conversion luminescence were studied. The glass ceramic obtained holds promise as a luminophore and makes it possible to obtain intense yellow luminescence by excitation in the IR range of the spectrum.
