Pectin is a high-molecular-weight carbohydrate polymer that has the capability to form hydrogel upon heating or blending with divalent cations. However, intrinsic pectin gels are weak and not enough functionalities. In this study, lanthanide ions and silk fibroin derived carbon dots had been included into Pectin/PVA hydrogel (PPH) to form luminescent difficult hydrogels. The luminescence for the hydrogel are tuned by adjusting the ratio of blue emission carbon dots to Eu3+ ions (red emission)
