Solvothermal Synthesis of Chitosan Quantum Dots Using Different Solvents

In this current research, carbon quantum dots were synthesized by solvothermal synthesis method, using different solvents. The different solvents which were used for synthesis of carbon dots were 5-Sulphosalicylic acid, and Salicylic acid. In this method 1 per cent salicylic acid and 2 per cent 5-Sulphosalicyic acid was used with ethanol in hydrothermal bomb for 4 hours at 140^oC. After the synthesis period a luminescence was seen with both the solvents. The solvents produced green, violet and blue fluorescence at different wavelengths of UV light.
