LED light extraction enhancement enabled using self-assembled particles patterned surface
Abstract:
A light emitting diode (LED) containing device including a light emitting diode (LED) structure, and a light transmissive substrate in contact with the LED structure. The light transmissive substrate has a texture surface tuned to include features with dimensions greater than a wavelength of light produced by the LED structure. In some embodiments, increasing the feature size of the texture to be comparable to the wavelength of light produced by the LED increases light extraction from the LED in comparison to when the feature size of the texture is substantially less or substantially larger than the wavelength of light.
