Findings revealed that the applied current significantly affected plasma properties such as electron temperature and density, which in turn influenced the structural and optical characteristics of the nanocomposite. The results indicated that electron temperature, density, crystallinity, and optical absorption of the nanocomposite increased proportionally with the applied current.<\/p>\n<p>The research also demonstrated that SiO\u2082\/Au nanocomposites hold promising applications in biomedical fields, renewable energy (such as solar cells), as well as in enhancing Raman spectroscopy.<\/p>\n<p>The thesis recommended the incorporation of silanization agents to improve the morphology of the external gold shell, thereby enhancing the plasmonic resonance and photocatalytic activity of the nanocomposite, which opens new horizons for both scientific and industrial applications.<\/p>\n<div id='gallery-1' class='gallery galleryid-5013 gallery-columns-1 gallery-size-full'><figure
