摘要/Abstract

摘要： 采用共沉淀法合成了一系列掺杂Eu3+，Dy3+的Zn3(BO3)2纳米发光材料，X射线衍射测定其物相为单斜晶系的Zn3(BO3)2，平均粒径为15～25?nm左右,同时研究了Eu3+，Dy3+掺杂样品的发光特性.在Eu3+和Dy3+共同掺杂的体系中，可以观察到由于Eu3+，Dy3+之间的能量传递使Eu3+强烈敏化Dy3+的发光现象.

关键词: 发光, Zn3(BO3)2纳米材料, Eu3+和Dy3+

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+.
