Fluorophosphate nanostructured glass ceramics activated by erbium ions
- 125 Downloads
Possibility of preparation of transparent nanostructured glass crystalline materials based on fluorophosphate glasses with high fluoride content is demonstrated. The influence of concentration of rare earth ions (REI) on the crystallization process is studied. We determined the conditions of heat treatment to form nanocrystals containing REI whose growth is evidenced by the results of X-ray phase analysis changes in the absorption and luminescence spectra and in the lifetime of the excited level of trivalent erbium.
