Synthesis and Photolumınescence Properties of Pb2+ -Doped Ca2B2O5
Abstract
Un-doped and a series of Pb2+ ion-doped UV-emitting Ca2-xPbxB2O5 (0.0025 ≤ x ≤ 0.03) phosphors were prepared via the solution combustion method, and their prospective luminescence properties were investigated. The formation of the monoclinic phase of Ca2B2O5 was confirmed by the powder X-ray diffraction result. The Ca2–xPbxB2O5 (0.0025 ≤ x ≤ 0.03) phosphors’ photoluminescence properties were examined using a spectrofluorometer at room temperature. The broadband peaking at 331 nm is the emission peak of Ca2B2O5:Pb2+ (0.01 mol), which is ascribed to the 3P1→1S0 transition. For Ca2B2O5, the relationship between the emission intensity and the Pb2+ content was thoroughly examined. Finally, utilizing the excitation band at 273 nm and the emission band at 331 nm, the Stokes shift of the prepared material, Ca2B2O5:Pb2+, was determined to be 6418 cm–1.
