Abstract

Layers of zinc oxide (ZnO) on glass substrates were grown by chemical bath deposition method. This method refers to solvo-thermal methods of crystal growth. When either ethylene-diamine-tetraacetic acid (EDTA) or ammonia was used as a complex agent, very weak adhesion of ZnO nanoparticles to the surface of glass substrates was noted, and when washing, the samples on the surfaces were removed by a water flow under pressure. When EDTA and ammonia were used together, the adhesion of ZnO nanoparticles to glass substrates increased dramatically. According to X-ray diffraction data, all sediments belong to the hexagonal syngony and correspond to the wurtzite-type ZnO structure. Optical absorption measurements showed that the band gap varied from 3.58 to 3.97 eV. The density of beams from ZnO nanowires on the substrate surface varied depending on the ratio between EDTA and ammonia.

ZnO纳米粒子化学沉积层的EDTA-氨比的优化

摘要

通过化学浴沉积法在玻璃基板上生长氧化锌（ZnO）层。该方法是指晶体生长的溶剂热法。当使用乙二胺四乙酸（EDTA）或氨水作为络合剂时，发现ZnO纳米粒子对玻璃基板表面的附着力非常弱，清洗时，通过水流将表面上的样品去除在压力之下。当EDTA和氨水一起使用时，ZnO纳米粒子对玻璃基板的粘附力急剧增加。根据X射线衍射数据，所有沉积物均属于六边形，并且属于纤锌矿型ZnO结构。光吸收测量表明，带隙在3.58至3.97 eV之间变化。
