▎ 摘　　要

The development of optically active polymer composites continues to be the research interest in the field of applied science. A polymer composite composed of polyvinyl butyral (PVB)/ Graphene Quantum Dots (GQD) that demonstrated significant photosensitivity has been studied in this work. A systematic influence of GQD on the photosensitivity to bandgap variation is observed. The surface morphology of loaded nano entities in the composites and their surface roughness was examined by TEM and AFM analysis.
