Abstract: Zn3(BO3)2 nanoparticles codoped with Eu3+ and Dy3+ were synthesized by coprecipitation method. Xray diffraction analysis shows that the phase of the particles is Zn3(BO3)2 of monoclinic system and their average diameter is 15～25 nm. The photoluminescent emission and excitation spectrum of the samples were studied systematically. In the Eu3+ and Dy3+ coactivated samples, the emission intensity of the Dy3+ ions is strongly enhanced because of the energy transfer process from Eu3+ to the Dy3+.

Key words: Zn3(BO3)2纳米材料, Eu3+和Dy3+ , 发光
