Device-spectroscopy of magnetic field effects in a polyfluorene organic light-emitting diode

open access: yes, 2007
We perform charge-induced absorption and electroluminescence spectroscopy in a polyfluorene organic magnetoresistive device. Our experiments allow us to measure the singlet exciton, triplet exciton and polaron densities in a live device under an applied ...

Top-Emission Organic Light Emitting Diode Fabrication Using High Dissipation Graphite Substrate

open access: yesInternational Journal of Photoenergy, 2014
This study uses a synthetic graphite fiber as the heat dissipation substrate for top-emission organic light emitting diode (TEOLED) to reduce the impact from joule heat. UV glue (YCD91) was spin coated onto the substrate as the insulation layer.
