Using rare earth coordination polymers with salicylic acid as precursors and composing with the polyvinyl alcohol (PVA) as dispersing media, EU3+, Tb3+, Ce3+ -activated Sr3Y(PO4)(3) phosphors with different doping concentration and Sr(3)y(PO4)(3): 3 mol % Pr3+ were prepared via an modified wet chemical technology. The emission intensities of activators have been found to depend strongly on the doping concentration. The result is that the optimum concentration for Eu3+ is 7 mol %, for Tb3+ is 9 mol % and for Ce3+ is 3 mol %, respectively. Furthermore, the crystal field depression value D (Ln, A) of Sr(3)y(PO4)(3) have been calculated to be 16, 895 cm(-1) when Ce3+ was doped in Sr(3)y(PO4)(3).
