我们展示了第一个白色发光器件起源于单碳点组件。当电流密度为5 mA cm（-2）时，其最大外量子效率为0.083%，显色指数为82，表明碳量子点具有很大的潜力成为制备白色电致发光器件的替代荧光粉。
We demonstrate the first white light-emitting device originating from single carbon dot components. A maximum external quantum efficiency of 0.083% at a current density of 5 mA cm(-2) with a color-rendering index of 82 is realized, indicating that carbon dots have great potential to be an alternative phosphor for fabricating white light electroluminescent devices.
