Abstract(in Japanese) (See Japanese page)
Abstract(in English) Bi-activated SrGa_2S_4 (SrGa_2S_4:Bi) phosphor exhibits green luminescence with a peak wavelength of 533nm and a full width half maximum (FWHM) of 55nm. This luminescence is due to the 6p-6s transition in the 6s^2 configuration of Bi^<3+>. As SrGa_2S_4 is co-activated by Bi^<3+> and Mn^<2+> ions, the excitation band around 400nm is enhanced relative to that around 300nm.
