Investigation of Chemical Resistance of Oxychloride Lead Borate Glasses Doped with Neodymium and the Stability of Their Luminescent Properties in the Climatic Conditions of South-East Asia.

The chemical resistance of glasses based on the PbCl2–PbO–B2O3–NdF3 system was studied. Oxochloride lead-borate glasses demonstrated satisfactory water resistance and alkali resistance, while low acid resistance. Bulk glass samples were exposed to the tropical climate of Southeast Asia for a year. The spectral-luminescent characteristics of neodymium ions in these matrices maintain good stability in a tropical climate. [ABSTRACT FROM AUTHOR]
