摘要：
Fluorescent polymer films, a matrix of thermoplastic starch (TPS) based bio-polymer and graphene quantum dots (GQDs) were fabricated by a casting method. The GQDs provide solid state fluorescent properties to the prepared thermoplastic starch graphene quantum dots (TPS/GQD). The fluorescent, thermal, mechanical and optical properties of TPS/GQD were investigated. High optical transparency (88-91%) and well dispersion of GQDs (1-17 wt%) in the polymeric matrix of TPS/GQD nanocomposite was observed. The maximum photoluminescence intensity of materials has been obtained at 50 wt% of GQD content. These materials have great potential to use in flexible electronic displays, light emitting diodes (LED), GQD-LED packaging and other optoelectronics applications.
