Abstract

Na2O-PbO-Al2O3-B2O3-SiO2 glasses mixed with different concentrations of MnO (ranging from 0.3 to 0.9 mol %) was prepared by melt quenching technique. The samples were characterized by X-ray diffraction technique, Optical absorption and Photo luminescence technique. A prepared glass sample is confirmed by X-ray diffraction spectra. The optical absorption spectra of these glasses exhibited a predominant broad band peak at 21,052 cm-1 (475 nm) is identified due to 6A1g (S) → 4T1g (G) octahedral transition of Mn2+ ion. From the spectral analysis the optical band gap (Eopt) and Urbach energy (ΔE) are evaluated. The emission spectra of Mn2+ doped titled glasses have shown single and broad emission band at about 600 nm assigned to electronic transition 4T1g (G) → 6A1g (S) displaying red emission upon excitation at 413 nm. Various principle physical properties were also evaluated.
