Abstract
A novel device using a LiF layer both at the anode-organic interface and at the cathode-organic interface was fabricated, combining a weakened hole in jection with enhanced electron injection. The device showed the highest lum inance of 21 000 cd/m(2) m(2) at a fixed bias of 12 V. The device exhibits a steeper I-V characteristic and a higher brightness than that of the devic es of other structures. The steeper I-V characteristic of the device may be useful to an organic electrically pumped laser. (C) 2001 Elsevier Science B.V. All rights reserved.
