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 nanomaterials were also investigated.The results showed that,for all studied Eu3+ doping concentrations,a single-crystalline phase of rhabdophane-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+.
