Highly crystallin. lumin.scen. n.n.phosphors of CePO4：DY^3＋ re-dispersible in.polar solven.s were successfully prepared via a simple polyol route at 140 ℃. As-prepared Dy^3＋ doped CePO4 n.n.phosphors prepared in.EG an. DMF appeared to have crystallin. mon.clin.c phase but exhibited hexagon.l phase when.prepared in.water an. water mixed solven.s, The hexagon.l phase tran.formed to mon.clin.c phase after heatin. at 900 ℃. TEM study revealed differen. shapes of the syn.hesized n.n.phosphors with chan.e of solven.s. The lumin.scen.e in.en.ity of 4F9/2→6H15/2 at 478 n. （blue） was foun. to be more promin.n. than.4F9/2→6H13/2 at 572 n. （yellow）. The in.roduction.of metal ion. （Li＋, Ba2＋ an. Bi3＋） in.CePO4：Dy3＋ led to con.iderable lumin.scen. en.an.emen.. The n.n.phosphors were subsequen.ly in.orporated in.polymer films of PVA which showed the characteristic emission. of Dy3＋. It also served as an.effective method to improve the performan.e of polymer materials an. brought about n.vel properties in.them.
