Abstract
In this article, we succeeded in identifying the absorption peaks that appear in the optical absorption spectra of chromium oxide thin films prepared by the pulsed laser deposition method. It was found that these peaks belong to the nanostructures in the film (chromium particles and chromium oxide nanoparticles). The study included investigating the effect of each of the substrate temperature and laser fluence on the prepared films. We found that heating the substrate to 327 °C leads to a decrease in the concentration chromium nanoparticles. In addition, we found that increasing the laser fluence to 36.7 J cm−2 leads to a significant increase of both the oxygen content and the chromium nanoparticle concentration in the film.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
