Green/green-yellow-emitting KSrGd(PO4)2:Ce3+, Tb3+/Mn2+ phosphors with high quantum efficiency for LEDs and FEDs.
Ce(3+), Tb(3+) and Mn(2+)-activated KSrGd(PO(4))(2) phosphors with high absolute quantum efficiencies were first prepared by a Pechini-type sol-gel method. The photoluminescence and cathodoluminescence intensities of Tb(3+)/Mn(2+) can be enhanced by co-doped Ce(3+) ions into the KSrGd(PO(4))(2) host via the energy transfer process.
