摘要：

In this work, the electrical and optical characteristics of top-emitting organic light-emitting device (TEOLED) using metal Ag as anode with different thicknesses have been investigated. The emission peak of fabricated TEOLED is 512 nm for a full-width at half-maximum (FWHM) of 48 nm in forward direction. The TEOLED turns on at 3 V with luminance of 2.38 cd/m(2) and reaches 16,300cd/m(2) at 9V. The maximum of current efficiency is 5.2cd/A at 7V, corresponding to the external quantum efficiency of 1.72%. (C) 2007 Elsevier Ltd. All rights reserved.
