Abstract
K3Gd(PO4)2:Tb3+ phosphors are synthesized by the solid reaction method, and the phases and
luminescence properties of the obtained phosphors are well characterized. The emission spectra of
K3Gd(PO4)2:Tb3+ exhibit the typical emissions of Tb3+. Concentration quenching of Tb3+ is not observed in
K3Gd(PO4)2:Tb3+, likely because the shortest average distance of Tb3+-Tb3+ in K3Gd(PO4)2:Tb3+ is adequately
long such that energy transfer between Tb3+-Tb3+ ions cannot take place effectively. This result indicates
that K3Tb(PO4)2 phosphors have potential application in near ultraviolet (n-UV)-convertible phosphors for
white light-emitting diodes.
