The surface morphology and optical properties of zinc oxide microstructures have been studied by scanning electron microscopy, photoluminescence and Raman spectroscopy. Microcrystals with transverse dimensions of 2–8 µm were studied. The Raman spectra of the studied samples were characterized by an anomalously high intensity, which was associated with the trapping of the exciting radiation in the minicavity cuvettes (photon traps). The high conversion efficiency of the exciting radiation into a Raman scattering signal is explained by the large value of the total path that the photon of the exciting radiation travels in a disperse medium in a photon trap. It was found that at room temperature quite intense photoluminescence is observed in zinc oxide microstructures in the region λmax = 385–390 nm upon excitation by the second optical harmonic (λex = 255.3 nm) of a copper vapor laser. The results obtained can be used to create new laser materials based on zinc oxide micro- and nanostructures. The developed original method based on photon traps opens up great prospects for detecting weak signals of secondary radiation of a wide class of inorganic and organic ultradisperse media.
