Abstract

The luminescence properties of a potential blue-emitting $RbBaPO_4:Eu^{2+}$ phosphor substituted with various metal ions have been investigated. The main emission wavelength of the phosphor samples was red-shifted by the substitution with K and Sr ions. The maximum peak intensity was obtained from the sample $Rb_{0.25}K_{0.75}Ba_{0.99}Eu_{0.01}PO_4$ which showed 144% relative intensity versus that of BAM:$Eu^{2+}$ phosphor under 254 nm excitation.
