Paper Abstract

Use of dielectric nanoparticles placed at the anode (indium tin oxide) for the improvement of light-extraction efficiency of an organic light-emitting diode (OLED) has been reported. The nanoparticle layer will act as a scattering medium for the light trapped in the waveguiding modes of the device. Mie theory has been applied to study the scattering efficiency of the isolated dielectric nanoparticle. The effect of dielectric nanoparticles on the light-extraction efficiency of OLED has been analyzed by the finite-difference time-domain method. The light-extraction efficiency of the device depends upon the diameter, interparticle separation, and refractive index of dielectric nanoparticles. At optimal nanoparticle parameters, the enhancement factor of 1.7 times is obtained with the proposed design.
