Nanowires/nanorods of europium/terbium orthophosphate monohydrate with Eu3+ concentration of 6,11,and 20 at.% were prepared by microwave synthesis method.The effects of Eu3+ doping concentration on structure,morphology and optical properties of nanoma-terials were also investigated.The results showed that,for all studied Eu3+ doping concentrations,a single-crystalline phase of rhabdo-phane-type(Eu,Tb) PO4·H2O nanowires/nanorods was obtained by using microwave heating of an aqueous solution of terbium(III) nitrate,europium(III) nitrate and NH4H2PO4 with pH=2.The length and width of these nanowires/nanorods ranged from 150 to 300 nm and from 10 to 50 nm,respectively.The evidence of energy transfer from Tb3+ to Eu3+ due to the energy overlap between the donor Tb3+ and the acceptor Eu3+ was observed obviously via a significant enhancement in the luminescent intensity of Eu3+.

The effects of Eu3 + doping concentration on structure, morphology and optical properties of nanoma-terials were also investigated. The results showed that, for all studied Eu3 + doping concentrations, a single-crystalline phase of rhabdo-phane-type (Eu, Tb) PO4 · H2O nanowires / nanorods was obtained by using microwave heating of an aqueous solution of terbium (III) nitrate , europium (III) nitrate and NH4H2PO4 with pH = 2. The length and width of these nanowires / nanorods ranged from 150 to 300 nm and from 10 to 50 nm, respectively. The evidence of energy transfer from Tb3 + to Eu3 + due to the energy overlap between the donor Tb3 + and the acceptor Eu3 + was observed obviously via the luminescent intensity of Eu3 +.
