Blue photoluminescent carbon quantum dots were successfully prepared by tuning the carbonization of citric acid from the pyrolysis reaction. Optical characterization of carbon quantum dots was investigated by UV-vis and fluorescence spectrometer. Quantum efficiencies of carbon quantum dots were obtained from fluorescence spectroscopy. Morphologies of carbon quantum dots were obtained using TEM. TEM image displays the carbon quantum dots with the size of about 5 nm. Carbon quantum dots were used to detect explosives such as nitroaromatic, nitramine, and nitrate ester compounds. An increase of photoluminescence from carbon quantum dots as a fluorescence turn-on sensor was measured upon the exposure of explosive compounds. The sensing mechanism of carbon quantum dots was investigated. This research was supported by Agency for Defense Development. This work was supported by the Human Resource Training Program for Regional Innovation through the Ministry of Education and National Research Foundation of Korea (NRF-2012H1B8A2026282)
