Luminescence Properties of Transition Metal and Rare Earth Doped Cadmium Lead Borophosphate Glass
Abstract:
Series of rare earth doped Cadmium Lead borophosphate glass were prepared using melt quenching technique and their luminescence properties were studied. Raw materials were mixed and preheat for 30 minutes, melted for 10 minutes without annealing process. With the composition of 30CdO:20PbO:10B2O3:40P2O5 host glass, 1 mol% of Neodymium Oxide, Ferum Oxide, Titanium Oxide and Yttrium Oxide were doped as activator to study the luminescence effect using Photoluminescence (PL) and Ultraviolet-Visible (UV-Vis) spectrophotometer. By exciting the samples at different wavelength (200-900 nm), the excitation and emission profile were obtained and analyzed to study the energy transfer process. Referring to the spectrum obtained, selected samples were co-doped among each other to obtain desired luminescence properties. Energy level diagram were plotted to discuss and explain the emission transition and mechanism. UV-Visible spectroscopy results reveal the absorption wavelength of samples for targeted application as band filter. Physical properties such as chemical stability and color of the samples were recorded to correlate with PL and UV-Vis result.
