| Abstract | ||
| Crystalline Ce3+ co-doped LaPO4:RE (RE=Dy3+, Tb3+, Eu3+, Sm3+) and mix doped rare earth ions of Dy3+, Tb3+ and Eu3+ were prepared by the polyol method at 150oC. Strongly enhance luminescence intensity is obtained with the co-doping of Ce3+ with LaPO4:Dy3+ and LaPO4:Tb3+ due to charge transfer (CT) occurring from Ce3+to Dy3+ and Ce3+ to Tb3+, where as there is no significant changes in luminescence intensity of Ce3+ co-doped Eu3+ and Sm3+ doped LaPO4 samples. The luminescence color can be tuned from green to white by varying the excitation wavelength for the mix ions Ce3+, Dy3+, Tb3+ and Eu3+ doped with LaPO4. | ||
