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:10B2O3:40P2O5host 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.

Studies of concentration dependences in the luminescence of Ti-doped Al2O3Abstract. 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-xMnO 2 -30B 2 O 3 -(50-x)P 2 O 5 -2TiO 2 where 0 x 20 were prepared using melt-quenching technique in air atmosphere. The samples containing different MnO 2 and P 2 O 5 content were both subjected to FT-IR testing to show the contrary effects of the network modifier. Infrared absorption spectrum shows vibrational bands of BO 4 and PO 3 structure within the borophosphate network structure, with the dominant BO units increasing with lower P 2 O 5 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.
A series of potassium lead borophosphate glass doped with rare earth and transition metal ions were fabricated using melt-quenching method without annealing process. With the composition of glass 0.15K 2 O -0.15PbO -0.35B 2 O 3 -0.5P 2 O 5 as host doped with 0.01 mole % of neodymium oxide, iron oxide, yttrium oxide, and titanium oxide as activator and different composition were used to investigate the luminescence effect by using Photoluminescence Spectroscopy and UV-Vis (Ultraviolet-Visible) 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. By referring to the spectra obtained, selected samples were also codoped among each other to obtain desired luminescence properties. UVVisible spectroscopy results revealed the absorption and transmission wavelength of samples for targeted application as a selected band filter. Physical properties such as chemical stability and color of the samples were also recorded to correlate with PL and UV-Vis result. Certain rare earth activated samples displayed slight coloring under the visible wavelength especially Nd 2+ ions doped samples displayed slight purplish.
