Abstract: 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.
