    Photoluminescence studies and synthesis of BaSO3Cl2:Ce3+ blue-emitting lamp phosphor
    (Wiley, 2021) Panse, V. R.; Zade, D. B.; Milind, Jog; Dhoble, S. J.; Cengiz, Korhan
    The photoluminescence excitation and emission spectra of BaSO3Cl2:Ce3+ phosphor were investigated. Excitation wavelength was 323 nm. The phosphor was prepared using a combustion synthesis method. The emission spectrum exhibited a well defined asymmetric band with a maximum at 445 nm for higher emission concentrations. The prepared samples were characterized by X-ray diffraction, scanning electron microscopy, photoluminescence and Commission Internationale de l'eclairage colour coordinates; emission intensity was related to relative Ce3+ concentration. These developments enabled the rapid and energy-efficient production of fine particles in the powder form with little expenditure. No additional emission band was observed in the emission spectra, demonstrating that the Ce3+ ion occupied one category of site in the prepared host phosphor.
