摘要

在这篇文章中，我们成功地确定了脉冲激光沉积法制备的氧化铬薄膜的光学吸收光谱中出现的吸收峰。研究发现，这些吸收峰属于薄膜中的纳米结构（铬颗粒和氧化铬纳米颗粒）。研究包括调查基底温度和激光能量对制备薄膜的影响。我们发现，将基底加热到 327 °C 会导致纳米铬颗粒浓度降低。此外，我们还发现，将激光通量提高到 36.7 J cm-2 会显著增加薄膜中的氧含量和铬纳米粒子浓度。

The Optical Properties of Nanoparticle Configurations in Cr/Cr2O3 Composites Synthesized by Pulsed Laser Deposition Method

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.
