| Abstract: | Ce~(3+)activated phosphors,fluorophosphate Na_2Gd_(0.99)Ce_(0.01)PO_4F_2 and polyphosphates MGd_(0.99)-Ce_(0.01) (PO_3)_4(M=Na,K,Cs),were prepared using a high-temperature solid-state reaction technique.Five excitation bands were observed at about 316,266,235,216,206 nm from Ce~(3+)5d in Na_2Gd_(0.99)Ce_(0.01)PO_4F_2, and two emission bands from Ce~(3+)5d-4f were found at about 350,375 nm.On the basis of these observations, it is assumed that Ce~(3+)ions occupy one lattice site in Na_2Gd_(0.99)Ce_(0.01)PO_4... |
