Concentrated Sulfuric Acid

A facile method is proposed to synthesize carbon quantum dots (C-dots) from citric acid using concentrated sulfuric acid as carbonization reagents with temperature below 100 °C during the whole process. The prepared C-dots has a Gaussian distribution in its lateral size with the average value around 6.37 nm. High quality of the C-dots is revealed through the optical performances such as sharp band-edge absorption, typical absorption peak and nearly excitation-independent blue emissions. Further, the pH condition is found to have correlation on the strong and stable photoluminescence property.
