Paper Abstract

A model based upon Mie theory was developed to calculate the level of scattering caused by the incorporation of a second-phase. Various transmission curves were calculated in order to study the microstructural scattering effects of pores and ZnGa2S4 particles. The model was able to reproduce the spectral transmission curve (2.5-10 micrometers ) of a hot-pressed ZnS sample containing a porous scatterer only when a size distribution effect was included in the model. A bimodal distribution of pores was found to be responsible for the detected scattering.
