Abstract

This paper reports the fabrication of a quantum dots (QD)-organics hybrids light-emitting diode (LED) for potential light sources. Organic light emitting diode (OLED) have become a focus of attention since past decades for potential light sources in a flat panel displays applications. Despite their intriguing performance in producing rich-color light emission, they still faced several critical defects, such as relatively low-brightness, low-chemical and photostability and short lifetime. Here, we demonstrate a novel system for the production of pure-color light emission with exceptionally high brightness by utilizing quantum dots that are hybridizing with light emitting organic materials, as an active material in light - emitting diode devices. Organic-quantum dots hybrid LED devices was fabricated by sandwiching the quantum dots monolayer between the electron transport layer (ETL) and hole transport layer (HTL) in a conventional OLED structure (ITO/ETL/QD/HTL/Al). Quantum dots of CdSe (ZnS) core-shell structure were function as the emitting layer. The ETL and HTL were poly(vinyl carbazol), PVK and tris(8-quinolinolato) aluminum(III), Alq3; respectively. The current-voltage (I-V) characterization on the device was found that the hybrid LED exhibited a strong blue emission under a relatively low bias voltage, of which their turn-on voltage was as low as 5.0 V.
