碳量子点在照明和显示器方面显示出潜力。然而，到目前为止只观察到它们的荧光。在这里，我们报告的聚乙烯醇基质中的碳量子点的磷光观察。磷光归因于碳量子点表面上的C=O键，并且具有非常长的寿命（类似于380 ms）。
Carbon dots show potential in lighting and displays. However, only their fluorescence has been observed so far. Here we report the observation of phosphorescence from carbon dots in a polyvinyl alcohol matrix. The phosphorescence is attributed to C=O bonds on the surface of carbon dots and has a very long lifetime (similar to 380 ms).
