Abstract

A high efficiency white light emitting diode (LED) was fabricated by generation of frequency down-conversion from a GaN/InGaN blue LED. In place of conventional inorganic phosphors, a perylene-based dye was used for colour conversion. The resulting hybrid structure is analysed by focusing on the visual performance of the realised LEDsemploying the most relevant photometric parameters of a light source.Preparation of the organic polymer is described as well. The thermalstability of the dye was investigated and a simple structure which avoidscolour degradation is proposed.
