Direct white light emission from carbon nanodots (C-dots) in solution processed light emitting diodes
We describe the preparation of inverted white light emitting diodes by solution processing. The active layer is formed uniquely by Carbon Nanodots (C-dots) that display white-light emission at voltage close to 5 V when combined with metal oxides as charge transport layers. Moreover, we have demonstr...

Summary: | We describe the preparation of inverted white light emitting diodes by solution processing. The active layer is formed uniquely by Carbon Nanodots (C-dots) that display white-light emission at voltage close to 5 V when combined with metal oxides as charge transport layers. Moreover, we have demonstrated that the white light is not the product of charge transfer between the polymer selective contact and the C-dots but the result of the different recombination processes within the C-dots.
C-Dots are the only component of the electroactive layer in solution processed LEDs and the only source of the white light. |
