Photo luminescence study of Eu doped, Mn codoped Bay2O4 phosphor with flux

The rare-earth Eu(1.5%)doped and Mn(1%,3%,5%) codoped BaY2O4 red phosphor with flux Citric acidis synthesized by solid state reaction method. The PLE, PL, XRD,SEM and FTIR were characterized. The excitation spectra of synthesized phosphor at 613 nm monitoring were composed of a broadband and a series of sharp peaks, the strongest excitation peak at 254 nm. The main emission spectra of samples under 254nm excitation is Eu3+ ions 5D0→7F2 electric dipole transition with a strong red light, so that the phosphors may be a better candidate for red component for white light generation in CRT and Compact Fluorescentlamps.
