Structural and luminescence study on titanium doped lead manganese borophosphate glass

Abstract

A series of lead manganese borophophate glass samples were prepared and studied to determine the structural and luminescence properties using Fourier Transform Infrared Spectroscopy (FT-IR) and Photoluminescence Spectrophotometer. The glass samples with composition of 20PbO-xMnO2-30B2O3-(50-x)P2O5-2TiO2 where 0 ≤ x ≤ 20 were prepared using melt-quenching technique in air atmosphere. The samples containing different MnO2 and P2O5 content were both subjected to FT-IR testing to show the contrary effects of the network modifier. Infrared absorption spectrum shows vibrational bands of BO4 and PO3 structure within the borophosphate network structure, with the dominant BO units increasing with lower P2O5 mol%. All glassy samples exhibit photoluminescence emission in the visible range. Manganese contained samples shows violet emissions while those without show violet-blue emission when excited by UV.
