In the present work, RE doped ZnO nano-powder has been successfully prepared by solid-state reaction. The products were obtained by doping commercial ZnO with 5% of three different rare earth elements; Europium Eu, Terbium Tb and Yttrium Y. The investigation results showed that the prepared materials exhibit predominant hexagonal wurtzite structure and have grain size between 20–65 nm. The band gap of the doped samples decreased from 3.212 to 3.137 eV; whereas, the optical absorption increased from 35% to 70%. The photoluminescence investigation showed that ZnO samples exhibit violet, blue and green emission that red shifts upon increasing structural distortion. Overall, the findings demonstrated the possibility of controlling ZnO visible light emission and control it to emit at a desired region that is beneficial for light emitting diodes and screen displays.

在目前的工作中，已经通过固相反应成功地制备了稀土掺杂的ZnO纳米粉。通过用5％的三种不同稀土元素掺杂商品ZnO获得产品。Eu Eu，T Tb和钇Y。研究结果表明，所制备的材料显示出主要的六方纤锌矿结构，晶粒尺寸在20-65 nm之间。掺杂样品的带隙从3.212降低到3.137 eV。而光吸收率从35％增加到70％。光致发光研究表明，ZnO样品表现出紫，蓝和绿发射，随着结构变形的增加，红移。总体，
