Abstract

Potassium-alumina-borate glass doped with chromium ions have been synthesized and investigated, and results are presented. We have synthesized glass of 25K2O-25Al2O3-50B2O3 speciation with addition of 0.2 weight per cent of Cr. It was found out, that heat treatment induces changes in absorption and photoluminescence spectra. According to x-ray diffraction measurements, it has been shown that Al4B2O9 nanocrystalls have been obtained. The average diameter of nanocrystalls is 15 nm. Luminescence spectra have shown that Cr3+ ions are in an octahedral crystalline surrounding of the alumina ions similar to the spectrum of ruby crystal. A conclusion has been done that nanocrystalls of Al4B2O9: Cr3+ are obtained, most probably, in the researched glass. Synthesized material can be used as the base for fiber amplifier in data-transmission systems and as an active substance for medical lasers.


Keywords: glass ceramics, potassium-alumina-borate glass, nanocrystall
