White light emission in alkali metal ion co-doped single host lattice phosphor Sr3B2O6:Ce3+, Eu2+, A+ [A=Li, Na and K]
چکیده انگلیسی
White light emitting alkali metal ion co-doped single host lattice phosphors Sr2.955B2O6:0.02Ce3+, 0.005Eu2+, 0.02A+ [A=Li, Na and K] were synthesized by high temperature solid state reaction. The synthesized phosphors were characterized by powder X-ray diffraction and Fourier transform infrared spectroscopic techniques. The optical properties were studied using diffuse reflectance UV-vis reflectance spectroscopy and photoluminescence (PL) spectroscopy. The role of Ce3+ as a sensitizer of Eu2+ was found from PL excitation results. The PL white light emission depends on the nature of co-doped alkali metal ion charge compensator.
