Abstract

The emission of yellow phosphor YAG:Ce3+ shows an asymmetric shape that causes the difficulty of spectrum modeling. We proposed and demonstrated a method for modeling the emission of yellow phosphor YAG:Ce3+. The mathematical model is developed based on the Gaussian function. The model's accuracy is quantitatively verified by comparing the simulation and experimental results. Normalized cross-correlation algorithms were applied to quantitatively define the similar level between the simulation and experiment results. The proposed model is helpful for emission spectrum modeling and efficient for studying the optical properties of yellow phosphor.
