Abstract

A new fabrication methodology for a nanostructured organic light-emitting diode (OLED), using a nanocrystalline metal-oxide film as a charge-injection electrode was investigated. A three-component multilayered LED was fabricated in which a monolayer of a light emitter was inserted between a nanostructured electron-transporting material (ETM) and a hole-transporting material (HTM). The use of distinct light-emitting and charge-transport layers offered greater flexibility for the choice of materials and energy-level matching. The LED performance was found to be enhanced by using a nanostructured device heterojunction as compared to the control device using a nonporous planar heterojunction. The methodology provides a wide range of nanostructured LED's, which provide increased flexibility in design and act as a versatile option for the future development of the electroluminescent devices. It also helps in enhancing the device performance.
