Transparent Polymer Light Emitting Devices utilizing MEH-PPV

Abstract

The transparent polymer light emitting device (TPLED) utilizing MEH-PPV that has the characteristics of transparency to visible range of light. By the insertion of BCP as an electron transport layer, the carrier and exciton were confined to enhance the recombination-rate, and BCP acts as a protecting layer from sputtering damage. Moreover, by alkali metal doping of the BCP, electron injection of the TPLED was improved. The device showed 70 % transparency at 590 nm, and the energy conversion efficiency from both surfaces of the device was 0.1 lm/W.
