Abstract

A process for preparing high efficiency light emitting devices (600) and the devices prepared using this process are described. High efficiency light emitting devices may be prepared by providing a layer of porous low refractive index material (602), such as an aerogel, between the emitting layer (605) of the device and the substrate (601). A method of preparing such light emitting devices comprising thermally patterning the layer of porous material of low refractive index is described. This method enables the preparation of high efficiency light emitting devices comprising porous low refractive materials using solution processing techniques.
