ANALYTICAL MODELS FOR PHOTO-EMISSION SPECTRA OF SINGLE COLOUR LEDS (PP33, 694-703)

We present an a priori analytic model for the photo-emission spectrum of single colour LEDs. The model establishes a close connection between the spectral properties of LEDs and the underlying solid state physics and can in principle be used to predict the photo-emission spectrum of an LED from only a few of its semiconductor properties. The full model is compared to a simpler, empiric, model by fitting the two models to a large set of experimental LED spectra. The simple model is well suited for good quality fitting of real LED spectra.
