Paper Abstract
Organic polymer red light-emitting devices (OPLEDs) with the double layer structure have been fabricated on flexible plastic substrates. Dow red emissive polymer and poly(3,4- ethylenedioxythiophene)/poly(styrene)(PEDOT/PSS) have been used as an emissive and a hole injection polymer, respectively. The spin coating technique was used to deposit different polymers. The absorption and the cyclic voltammetry spectra have been used to construct the band diagram of our OPLEDs. The following electrical and optical properties have been obtained for our OPLEDs: turn-on voltage, defined at 1 cd/m2=~3.0V; voltage and current density defined at 100 cd/m2=~6.5V and ~34mA/cm2; maximum emission efficiency =~0.25 cd/A; and maximum luminous efficiency =~0.1m/W. The extrapolated lifetime of unpackaged OPLEDs on flexible plastic substrate of about 1160 min for initial brightness of 100 cd/m2 has been obtained.
