The hydrothermal method of obtaining nano zinc oxide doped with different contents of aluminum ions (III) was presented and discussed in this paper. Aqueous solution of Zn(NO)*6HO and Al(NO)*9HO salts mixture were used as the synthesis precursor. In order to reduce the process time all reactions were performed in a microwave reactor. The influence of process parameters and the content of impurity ions on the properties of synthesized nano zinc oxide were analyzed. In addition to zinc oxide doped with Al(III) ions, an additional spinel phase (ZnAlO) was obtained. The luminescent properties of nano zinc oxide as a function of the dopant ions were also discussed. Based on the luminescence measurements results, it was found that the luminescence intensity decreases with the increasing dopant content. The obtained materials are aimed to be implemented as luminescent materials in optoelectronic and sensors.
本文介绍并讨论了通过水热法制备不同铝离子(III)掺杂量的纳米氧化锌。使用硝酸锌六水合物(Zn(NO₃)₂·6H₂O)和硝酸铝九水合物(Al(NO₃)₃·9H₂O)的混合水溶液作为合成前驱体。为了缩短工艺时间,所有反应均在微波反应器中进行。分析了工艺参数和杂质离子含量对合成纳米氧化锌性能的影响。除了铝(III)离子掺杂的氧化锌外,还获得了额外的尖晶石相(ZnAl₂O₄)。还讨论了纳米氧化锌作为掺杂离子函数的发光特性。基于发光测量结果,发现发光强度随掺杂剂含量的增加而降低。所获得的材料旨在用作光电子和传感器中的发光材料。
