摘要
Selective and sensitive water content measurement in organic solvents is extremely significant for both industrial use and laboratory preparation. Carbon nanodots are promising carbon nanomaterials with unique and novel properties and thus have drawn growing attention. However, the hydrothermal approach for the preparation of carbon dots always uses water as solvent, and consequently, the development of carbon dots from biomass materials for fluorescence detection of water content remains unexplored. Here, carbon dots were prepared from gallic acid via a cheap and facile one-step method. The as-prepared carbon dots present excellent sensitivity and selectivity toward water content and exhibits good linear relationships with water content in range of 0-10%. The carbon dots demonstrated a strong antioxidation capacity and colour-reaction of Fe3+ like gallic acid. The carbon dots also showed solid-state lighting.
