Control of morphology and luminescense of nanostructured ZnO layers for lasing applications

A comparative analysis of various technological methods for the preparation of nanostructured ZnO films is performed in this work to identify technologies suitable for the development of laser structures. It is shown that arrays of nanorods with a regular hexagonal geometry are readily produced by l...
