Zainelabdin S. Zaman G. Amin O. Nur M. Willander Received 7 April 2010 Accepted 24 May 2010 Published online 4 June 2010 The Author s 2010. This article is published with open access at Springerlink.com Abstract Stable intrinsic white light-emitting diodes were fabricated from c-axially oriented ZnO nanorods NRs grown at 50 C via the chemical bath deposition on top of a multi-layered poly 9 9-dioctylfluorene-co-N- 4-butylpheneylamine diphenylamine poly 9 9dioctyl-fluorene deposited on PEDOT PSS on highly flexible plastic substrate. The low growth temperature enables the use of a variety of flexible plastic substrates. The fabricated flexible white light-emitting diode FWLED demonstrated good electrical properties and a single broad white emission peak extending from 420 nm and up to 800 nm combining the blue light emission of the polyflourene PFO polymer layer with the deep level emission DLEs of ZnO NRs. The influence of the temperature variations on the FWLED white emissions characteristics was studied and the devices exhibited high operation stability. Our results are promising for the development of white lighting sources using existing lighting glass bulbs tubes and armature technologies.
