摘要：
An influence of pulsed laser radiation on the properties of monolayer of copper-based planar nanosnructures has been investigated. Novel data are obtained on optical and physico-chemical characteristics of the nanosnructures. Plasmon resonances shift, spectral properties and luminescent intensity of films are explained by the effects of metal particles oxidation and aggregation. The laser induced changes of physico-chemical characteristics were obtained from optical and AFM measurements. It has been shown that effect of nanostructure transformations depends on intensity of pulse laser, metal particles concentration and initial level of particles oxidation.
