Synthesis and Characterization of  CQDs from Carbon Soot of Almond Oil and It's Hierarchical Arrangement in 6CHBT LC media: Role of Functionalization

Abstract

We have synthesized carbon quantum dots (CQDs) from the carbon soot of almond oil deposited on copper metal surface. We have functionalized CQDs using 2,5-Dimercapto-1,3,4-Thiadiazole (DMTD), and have explored the integration of functionalized CQDs in 6CHBT LC media. Our primary objective is to investigate the effect of functionalized CQDs on the organizational behavior and the opto-electronic properties of the hybrid systems. We perform comprehensive characterizations such as FTIR (Fourier transform infrared spectroscopy), SEM (Scanning electron microscopy), OM (Optical microscopy), HR-XRD, UV-Vis-Nir, SERS and Fluorescence spectroscopy to explore the nano-micro scale hierarchical structures composed of CQDs owing to their self-assembly in presence of 6CHBT molecules. Our findings may pave the path for the development of novel integrated materials by tailoring opto-electronic properties. We have highlighted the role of surface plasmons by characterizing for surface enhanced Raman spectroscopy.
