Effect of dielectric nanoparticles on light extraction efficiency of OLED
2015 Workshop on Recent Advances in Photonics (WRAP), 2015We report enhancement in light extraction efficiency of organic light emitting diode (OLED) using dielectric nano-particles between glass substrate and anode. The nano-particles acted as a scattering medium for the light trapped in waveguiding modes of the device.

Enhancing the light extraction efficiency of GaN-based LEDs
SPIE Proceedings, 2007GaN-based light-emitting diode (LED) has been widely used in recent years, and tremendous progress has been achieved in GaN-based semiconductor materials and relevant process. However, owing to the large refractive index contrast between GaN-based semiconductor materials and air, light can be easily totally internally reflected at the semiconductor/air

Physics of light extraction efficiency in planar microcavity light-emitting diodes
1999We use the modifications of spatial mode distributions in planar microcavities to address the issue of light outcoupling in devices such as LEDs. Whereas detailed calculations are needed to fully model and optimize the structures, we show that a simple picture can be obtained that clarifies the main physical effects of the microcavity.

Improved Light Extraction Efficiency in GaN-Based Light Emitting Diodes
2011The improvement in light extraction efficiency (LEE) of GaN-based LEDs is one of the most important areas for increasing the external quantum efficiency for solid-state lighting applications. We summarize the advances in this field. GaN-based light-emitting diodes (LEDs) have made a lot of progress with regard to growth, doping, and p-ohmic contacts [1–

Photonic crystal structures for efficient localization or extraction of light
2002Three-dimensional (3D) photonic crystals offer the opportunity of light manipulation in all directions in space, but they are very difficult to fabricate. On the other hand, planar photonic crystals are much simpler to make, but they exhibit only a "quasi-3D" confinement, resulting from the combined action of 2D photonic crystal and internal reflection.
