Abstract

The aim of this paper is to study the behavior of the emission spectrum when there is a spectral interference or a spatial interference between the LEDs. Several heterojunction LEDs were desgined and modeled using COMSOL multiphysics. The simulated LEDs showed 3.75% average mismatch to the measured UV-Vis-NIR LEDs spectra. The heterojunction LED showed that the relative intensity has a direct proportional relation to the spectral interference and an inversely proportional relation to the spatial distribution. Moreover, the cool white LED was constructed using the royal blue LED and the yellow LED.
