摘要

采用化学水热沉积法合成了掺杂过渡金属Ni或Co的ZnO。SEM研究表明，在硅晶片上制备的ZnO薄膜由直径可达1 μm的纳米晶体组成，30 nm ALD ZnO亚层将水热生长的ZnO薄膜结构改变为密集排列的柱状结构。结果表明，与未掺杂ZnO晶体相比，掺杂Ni和Co使ZnO晶体的激子光致发光带减小。

Doping ZnO Hydrothermally Deposited Nanocrystals with Transitional Metals

The ZnO doped with transitional metals - Ni or Co - were synthesized by chemical hydrothermal deposition. According to SEM study ZnO films obtained on Si wafers consist of separated nanocrystals with diameter up to 1 μm, 30 nm ALD ZnO sublayer changed the structure of hydrothermally grown ZnO films to array of densely packed pillars. It was shown that doping ZnO with Ni and Co decreased the exciton photoluminescence band compared to undoped ZnO crystals.
