Herein, we have synthesized a highly fluorescent carbon dots from waste tea residue (WTR-CDs). The carbon dots have been synthesized by simple and cost-effective method i.e., carbonization of dried waste tea powder at 200 C for 5 hrs having distinguishable and tunable optical properties. The highly fluorescent WTR-CDS having λem = 460 nm at 380 nm as an excitation with excitation dependent emission obtained. These carbon dots can be easily embedded into polymer network by physical or chemical crosslinking to form carbon based composite hydrogels. The surface functionalities like -OH, -NH2, -COOH, etc., present on carbon dots and polymers make hydrogels more interactive, and stimuli (pH and temperature) responsive. The carbon-based composite hydrogels are the new class of materials having special and distinguishable physicochemical properties which showing multifaceted applications in drug delivery, water treatment, environmental remediation, as a sensing probe, and biomedical applications etc.
