Description

We study the transport of light in the visible wavelength range through silicone plates filled with YAG:Ce3+ phosphor particles that are used for white LEDs. We used P3 approximation to fully describes the light propagation in these plates that reveal a strong absorption up to L/la = 4, where L is the slab thickness, la is the absorption mean free path. Our approach is a suitable analytical tool for industry, since it provides a fast and accurate determination of key transport parameters, and possess predictive power in the design process of white LEDs.
