In addition, we suspect that the difference in C-dots emissions is caused by the molecular density and content of the preparation based on the concentration of precursor solutions and the length of microwave time.Īlgarra, M., Campos, B. This phenomenon is known from the top of the broad C-dots emission spectrum and shifts to longer wavelengths. The core energy level becomes dominant in the transition π→π* compared to the transition of n→π* in surface energy when the C-dots concentration increases so that energy shifts. The observed optical properties aim to determine the C-dots energy transition, such as surface and core energy. C-dots are characterized to study the optical properties of the UV-Vis absorbance spectrum and emission intensity in the form of emissions. Microwave duration causes changes in the structure and optical properties of C-dots. Synthesis of C-dots was carried out using water as a solvent with a variation of the concentration of precursor solutions to the microwave duration. Synthesis of C-dots from the outer shell of dried cassava has been successfully carried out with Microwave techniques. The outer shell of cassava is the second waste obtained from cassava skin waste which is less attention to be utilized.
