Abstract

Zinc oxide (ZnO) nanorods were manufactured using the aqueous chemical growth (ACG) method, and the effect of thermal acetylene treatment on their morphology, chemical composition, and optical properties was investigated. Changes in the elemental content of the treated rods were found to be different than in previous reports, possibly due to the different defect concentrations in the samples, highlighting the importance of synthesis method selection for the process. Acetylene treatment resulted in a significant improvement of the ultraviolet photoluminescence of the rods. The greatest increase in emission intensity was recorded on ZnO rods treated at the temperature of 825 °C. The findings imply that the changes brought on by the treatment are limited to the surface of the ZnO rods.

摘要

采用水热化学生长（ACG）法制备了氧化锌（ZnO）纳米棒，并研究了热乙炔处理对其形貌、化学成分和光学性能的影响。发现处理后棒材元素含量的变化与先前报道不同，这可能是由于样品中缺陷浓度不同所致，突出了合成方法选择对该过程的重要性。乙炔处理使棒材的紫外光致发光性能得到显著改善。在825℃温度下处理的ZnO棒上记录到发射强度的最大增加。研究结果表明，处理带来的变化仅限于ZnO棒的表面。
