Abstract

Quantum dots was successfully synthesized from orange peel by hydrothermal-assisted green method. The XRD analysis result shows that our sample has quantum dots peaks. From the EDAX analysis result, we found that the carbon structure is formed with a weight percentage of 66%, and the presence of the oxygen element is due to the exitant of functional groups and the activation of the surface of the quantum dots, and these group functionals (hydroxyl and depoxy) were also observed in the FTIR analysis. From the FESEM analysis, the sample has a spherical shape. From the examination of the optical properties, we found that the sample shows the most fluorescence properties at the excitation wavelength of 350 nm and has a green color under the UV lamp. XRD, EDAX, FTIR and FESEM analyzes were used to investigation the group functionals and structural properties. To investigated the optical properties, UV-Visible and PL analyzes were used.
