Zainelabdin, A. and Zaman, S. and Amin, G. and Nur, O. and Willander, M. (2010) Stable White Light Electroluminescence from Highly Flexible Polymer/ZnO Nanorods Hybrid Heterojunction Grown at 50Â°C. Nanoscale Research Letters, 5 (9). pp. 1442-1448.
Stable intrinsic white lightâ€“emitting diodes were fabricated from c-axially oriented ZnO nanorods (NRs) grown at 50Â°C via the chemical bath deposition on top of a multi-layered poly(9,9-dioctylfluorene-coâ€“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 lightâ€“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.
