Photoluminescence properties of combustion synthesized BaB 2O 4:Pb2+ phosphor A. B. Gawande, R. P. Sonekar, S. K. Omanwar Combustion Science and Technology, 2014 Inorganic borate host phosphor BaB2O4 doped with varying concentrations of Pb2+ has been prepared by a solution combustion synthesis technique. The synthesis is based on the exothermic reaction between the fuel (urea) and oxidizer (ammonium nitrate). The photoluminescence properties of prepared materials were studied at room temperature. Under the excitation of 240 nm, the phosphor BaB2O4:Pb2+ shows broad emission at 370 nm (corresponds to 3P1 to 1S0 transition). The optimum concentration of Pb2+ in BaB2O4:Pb2+ was found to be 0.02 mol (relative to Ba). The critical transfer distances, R0 were calculated. Stokes shifts were calculated (using corresponding excitation and emission band peaks) to be 14,640 cm−1. The emission bands of synthesized phosphors are in the ultraviolet (UV) region and could be potential candidates for application in UV lamps.
Combustion synthesis and energy transfer mechanism of Bi3+ → Gd3+ and Pr3+ → Gd3+ in YBO 3 A. B. Gawande, R. P. Sonekar, S. K. Omanwar Combustion Science and Technology, 2014 YBO3:Gd3+, YBO3:Gd3+, Bi3+, and YBO3:Gd3+, Pr3+ phosphors were synthesized by the combustion synthesis method. The phase analysis of all synthesized materials was determined using powder X-ray diffraction (XRD). Photoluminescence properties and concentration quenching of these phosphors were systematically investigated. All the samples show the characteristic narrow band UVB emission of Gd3+ ions (6PJ → 8S7/2). The maximum intensity of luminescence in synthesized materials was investigated. The energy transfer mechanism was studied using Bi3+ and Pr3+ as sensitizers, and it is observed that as compared to Bi3+, Pr3+ effectively transfers its energy to Gd3+. The Stokes shifts of YBO3:Gd3+, YBO3:Gd3+–Bi3+, and YBO3:Gd3+–Pr3+ phosphors were calculated to be 4181 cm−1, 6410 cm−1, and 7949 cm−1, respectively.
