ABSTRACT |
properties of $Sr_{1-x}Ba_xTiO_3:Pr$, Al red phosphor for Field Emission Displays (FEDs) have been investigated in powders prepared though solid-state reactions. $Sr_{1-x}Ba_xTiO_3:Pr$, Al red phosphors indicate a higher luminescent intensity, and have been found to have potential for field emission displays. The addition of Ba increased the luminescence intensity at 617 nm by up to 30%. Ba ions are effective in producing the energy transfers from host-to-activator in 4f-5d transitions. 뤀 대ᣗﺖ⨀ ޚ䜄 삥잖⨀ 䀠 ꀰ⨀ 큒⨀ Ă 䀠 煥獣愠獵扨敡瀀 ソソソソ ᇘ 돐胊ﺖ⨀ |
