Carbon Dots (CDs) are materials that play a role in non-toxicity, biocompatibility, high photostability, changeable photoluminence, high solubility, and easy functionalization. Cellullose Nanofiber (CNF) is an environmentally friendly polymer that has biodegrability, good dispersion capabilities, and able to optimize material characteristics. In this research, CNF was added to the CDS synthesis process to determine the effect of CNF on CDs optical properties. CDs were characterized using Fourier-transform Infrared Spectroscopy (FTIR) to determine the chemical bond content on CDs. Absorbance properties with a UV-Vis spectrometer. Photoluminence properties using a photoluminescent (PL) spectrometer. The results of FTIR characterization obtained indicate that the CNF obtained can maintain the chemical bonds formed on the CD. From the UV-Vis results, the CNF approval gives an increase in the intensity of NIR absorbance from the CDs. While based on the result of PL characterization, there is a decrease in emission intensity from the resulting CDs.
