| 英文摘要 | Low-voltage and multicolor electroluminescent light-emitting diodes (leds) based upon carbon dots (cds) are demonstrated by using simple all-inorganic cds/si heterostructures. electroluminescence (el) originations of the cds/si leds are investigated clearly without the interference of commonly used organic semiconductors. three distinct peaks at 438, 540, and 600nm are achieved in the el spectra of the cds/si leds, and they are found to only originate from the cds. addition of a pmma polymer does not influence the el originations, but improves the flatness of the cd active layer, thereby enhancing the el performance of the cds/si leds. most strikingly, the emission threshold voltage of such all-inorganic cds/si leds is as low as 3.4v, which is the lowest onset voltage among the cds-based leds by using fluorescent cds as the active emitter. the ultra-low driving voltage proves the feasibility of the all-inorganic cds/si leds in the future multicolor solid-state lighting applications. |
