Quantitative description of the microstructure of polyurethane nanocomposites with YAG including Tb3+

This paper presents the application of quantitative image analysis for the description of morphological properties of nanocomposites with YAG:Tb. Fracture images of YAG:Tb and nanocomposites were obtained using a high-resolution scanning electron microscope (HR-SEM) and atomic force microscopy (AFM). Quantitative analysis of the images obtained provided an explanation of the mechanism for changes in optical properties of polyurethane (PUR) nanocomposites. It also enabled the determination of the relationship between the structural characteristics and the properties of materials.
