Photoinduced charge transfer interaction between citrus limon extract passivated colloidal CdS with Methyl Violet & Beta Vulgaris dyes

Recently, use of different plant extracts for the green synthesis CdS nanoparticles has appealed significant attention throughout world. The components contained in antioxidant rich citrus fruits e.g. orange and lemon have attracted due to their chemical biological properties. To date, using limon extract as a surface functionalizing agent not been explored. In present study reliable method was developed by introducing Citrus Limon Extract (CLE) new development colloidal quantum dots (CCQDs). Photo induced interaction between CLE functionalized with Methyl Violet (MV) & Beta Vulgaris (BV) dyes Dyes adsorption on results quenching dye molecules emission intensity. UV–Visible spectroscopic studies evidently reveal idiosyncratic photo-induced charge transfer QDs noticeably differs from its dye. vulgaris shows H-aggregation capped QD surface. Photo-induced both attributed electron (e-) conduction band (CB) excited state dyes.
