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 (1-17wt%) in the polymeric matrix of TPS/GQD nanocomposite was observed. The maximum photoluminescence intensity of materials has been obtained at 50wt% 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.
荧光聚合物薄膜是通过浇铸法制备的，其基质为热塑性淀粉（TPS）基生物聚合物和石墨烯量子点（GQDs）。GQDs 为制备的热塑性淀粉石墨烯量子点（TPS/GQD）提供了固态荧光性能。研究了 TPS/GQD 的荧光、热、机械和光学性能。在 TPS/GQD 纳米复合材料的聚合物基质中观察到高光学透明度（88-91%）和 GQDs 的良好分散（1-17wt%）。在 GQD 含量为 50wt%时，材料的最大光致发光强度得到了获得。这些材料在柔性电子显示器、发光二极管（LED）、GQD-LED 封装和其他光电应用中具有很大的应用潜力。
