Abstract

A facile and green method has been demonstrated to synthesize ultrasmall tungsten oxide quantum dots (WO_x QDs). The water-soluble WO_x QDs present high luminescence stability, strong peroxidase-like activity, and excellent electrochemiluminescence properties. This work provides an eco-friendly strategy to prepare multifunctional WO_x QDs, and opens the door for bioapplications of the WO_x QDs.
