| Abstract: |
An optical model of a heterogeneous light-converting film based on a YAG:Ce3+ photoluminescent phosphor in epoxy resin is considered. The dependence of the distance between the phosphor microparticles in the suspension on the mass fraction of the powder and the densities of the components of the initial suspension is determined. Within the framework of the proposed model of the composite film, the coefficients of specular reflection and transmission within the region of isotropic scattering are simulated. It is demonstrated that optimizing the material composition by the amount of the photoluminescent component allows one to significantly reduce the coefficient of specular reflection of the UV pump radiation.
