Investigation of Manganese Oxide (MnO₂) Doped in Calcium Sodium Borosilicate Glasses for Photonics Materials Application

Abstract

In this work, MnO₂ doped in calcium sodium borosilicate (CNBS) glasses was investigated. The glass samples doped with MnO₂ were synthesized by the melt quenching method. The structural, physical, optical, and photoluminescence properties were examined and discussed. The X-ray diffraction spectra of the CNBS glasses. There are no sharp peaks to be seen, indicating the amorphous nature of the glasses. The optical absorption in the UV–Vis region showed a broad absorption band around 470 nm. The intensity band of absorption spectra increases with increasing of MnO₂ concentration. The luminescence spectra were measured and exhibited intense yellow emissions under 417 nm excitation. The results indicate that the glasses may be suitable for the development of optical material application in the yellow region.
