For the synthesis of white-light phosphor, red Eu3+ with different concentrations was co-doped into the blue LaPO4:Tm phosphor. It was found that the luminance at wavelength of 454 nm decreased gradually; on the contrary, reddish-orange emission at wavelength 594 nm was strengthened when the Eu3+ concentration was increased. The maximum red luminescent intensity was obtained when 7 mol% of Eu3+ was...
This paper describes the optical characteristics of indium- and tungsten-doped ZnGa2O4 phosphor for field emission display (FED). The solid-state reaction is used to synthesize the phosphor powder, and the phosphor film is prepared by electrophoresis. Indium doping enhances the luminescence of ZnGa2O4 phosphor; nevertheless, the emission of phosphor doped by tungsten shifts to the short wavelength...
