Polymeric carbon quantum dots as efficient chlorophyll sensor-analysis based on experimental and computational investigation

This report introduces a microfiber chlorophyll sensor based on polymeric amine functionalized carbon quantum dots (NCQD) using the surface plasmon resonance technique. The silver (Ag) thin film, followed by NCQD-polyvinyl alcohol composite film, was deposited on the tapered optical fiber. The chara...
