Influence of Morphological and Dimensional Parameters on Cathodoluminescent Properties of ZNO Microstructure Ensemble

The influence of morphological and dimensional parameters of the ensemble of ZnO microstructures on emission spectra when excited by a stream of fast electrons is studied. The research objects are arrays of viscers, tetrapods, and submicron ZnO particles. It was found that the red shift of the exciton luminescence band in ZnO microstructures is associated with their destruction and enrichment of charge carriers and maximum for an array of submicron particles. In the ZnO whisker array, when irradiated with the stream of fast electrons, an increase in the luminescence band associated with recombination of electron-hole plasma is observed.
