Аннотация
The opal-zinc oxide nanocomposite formed by chemical deposition from a solution has been investigated. Zinc oxide nanocrystals deposited on a substrate have a shape of truncated cones, which is characteristic of ZnO single crystals and exhibit good emission characteristics. However, in opal—ZnO nanocomposite, the exciton luminescence is suppressed, while the emission from the opal matrix is enhanced. The possible mechanisms of the observed effect are discussed.
