Synthesis of highly fluorescent phosphors has been established by means of incorporating carbon nanodots (CDs) with starch particles. Functionalized carboxyl and amide groups are confined on the external surface of CDs while the external surfaces of starch particles encompass numerous amount of Hydroxyl. As a result, effective adsorption between CDs and starch particles can occur via hydrogen bonding. Highly luminescent CDs/starch particles and silicone resins were combined to generate efficient uniform monolayer arrays of CDs/starch powder. Uniform CDs/starch powders were subsequently applied to Gold (Au) substrates. Hereupon, the photoluminescence and average lifetime of uniform CDs/starch particles were measured for further quality verification and observation of competent photoluminescence quantum yield. Extensively, the temperature-photoluminescence has been examined for potential utilization.
