Abstract

Optical absorption, infra-red absorption spectra and differential scanning calorimetry of amorphous (Na2B4O7)80-(Pb3O4)20-x -(CuO) x systems were studied as functions of copper content up to 10 mol%. When the Pb3O4 in the glasses is gradually replaced by CuO, a pronounced decrease in the optical energy gap and an increase in the optical absorption at 750 nm due to the CU2+ ions is observed. The change in the optical absorption may be attributed to the concentration variation of the Cu2+ ions in the glasses as a consequence of changing the lead content.
