EFFECTS OF HYDROTHERMAL CONDITIONS ON OPTICAL PROPERTIES OF GOURD-BASED CARBON NANOPARTICLES
Main Article Content
Abstract
In this study, we investigated the influence of hydrothermal conditions (hydrothermal temperature, precursor mass, and hydrothermal time) on the optical properties of gourd-based carbon nanoparticles (CNPs) synthesized by hydrothermal methods. Factors such as temperature, precursor mass, and hydrothermal time were investigated. Transmission electron microscopy imaging, Energy dispersive X-ray spectroscopy, X-ray diffraction, and Raman scattering spectroscopy were utilized to analyze the morphology, elemental composition, and structure of CNPs. Photoluminescence spectroscopy was used to compare the photoluminescence intensity and study the influence of hydrothermal conditions on the optical properties of CNPs. Research results show that the produced CNPs have particle sizes distributed widely from 10 nm to 100 nm. The photoluminescence spectrum of CNPs is strongest when excited at a wavelength of 350 nm. In this study, CNPs synthesized by hydrothermally heating 4 g of gourd at 220˚C for 12 hours offered the strongest photoluminescence intensity.
