Fluorescent Property of Carbon Nanodots Synthesized by Microwave Method from Crystal Nanocellulose as Precursor

Abstract

Carbon nanodots (CDots) are nanoparticles that can be synthesized from various carbon sources. In synthesizing the Dots by using carbon source from oil palm empty fruit as raw material, cellulose could become a potential source. Cellulose nanocrystals were utilized as precursors, and the Cdots were obtained by using microwave method. In this study, CDots synthesis using microwave method has been successfully done. From FTIR analysis, cellulose isolated from oil palm empty fruit showed functional groups which corresponded to neat cellulose. And for TEM analysis showed rod forms needles arranged variously, and they have diameter length about 10, 9nm. The physical properties of Cdotswere obtained in the most optimum parameters during the conditions of 1000 watts for 20 minutes. The obtained results were dark brown colour with green-to-blue fluorescent under UV light source. From this study, it can be concluded that CDots can be synthesized from cellulose nanocrystals.
