The effect of morphology on the optical and X-ray luminescence properties of an ensemble of zinc oxide microrods on single-crystal sapphire substrates has been studied. It has been shown that the intensity of X-ray luminescence depends on the volume of the ZnO single-crystal phase and the corresponding effective density of the absorbing medium. It has been found that the total transmission spectra of the samples have a complex structure. The transmittance primarily depends on the conditions of synthesis and nucleation, on the morphology of ZnO microrods, and on the degree of their misorientation in an ensemble. An array of ZnO microrods characterized by the rapid component of the X-ray luminescence kinetics in the range of 0–5 ns with a descending time of about 0.7 ns (taking into account the pump pulse) has been obtained.

研究了形态对蓝宝石衬底上单晶氧化锌微棒的光学和X射线发光特性的影响。已经表明，X射线发光的强度取决于ZnO单晶相的体积和相应的吸收介质的有效密度。已经发现，样品的总透射光谱具有复杂的结构。透射率主要取决于合成和成核的条件，ZnO微棒的形态以及其整体中取向不良的程度。已获得一系列ZnO微棒，其特征是X射线发光动力学的快速分量在0-5 ns范围内，下降时间约为0.7 ns（考虑到泵浦脉冲）。
