چکیده

The theory of optical properties of nanoparticles is considered with the aid of dispersion relations, which are based on the Kramers-Kronig analysis. It is shown that one can utilize rather general dispersion relations, which hold for liquid matrices that contain nanoparticles. Wiener bounds incorporating the Kramers-Kronig analysis are utilized in assessment of the complex permittivity of a nanoparticle.

The Preparation, structural characterization, optical properties, and antibacterial activity of the CuO/Cu2O nanocomposites prepared by the facile thermal decomposition of a new copper precursor

Objective(s): In this study, a new copper precursor was prepared from the combination of Cu(CH3COO)2∙H2O (1 g in 5 ml of methanol) and benzoic acid (1 g in 5 ml of methanol) at room temperature. Following that, the copper precursor was calcined at the temperature of 500ºC and 600ºC for 1.5 hours to form CuO/Cu2O nanocomposites with the code numbers of CuO-1 and CuO-2, respectively. Materi...
