Theoretical Review of Optical Properties of Nanoparticles

Nanoparticles are used in a variety of applications and their usage is growing vastly because of their superior characteristics, such as high specific area of contact, great mechanical properties, high electrical conductivity, and high optical scattering efficiency.. Among these numerous properties, optical properties play an important role in either the type of application in which nanoparticles may be utilized or the type of the nanoparticle which may be used for a desired outcome. Many textile products including fibers, fabrics, and textile composites benefit from these capacities of nanoparticles. This paper is a review about the theoretical methods for obtaining optical properties of nanoparticles, noticing that the particle type is selected based on generally used particles like TiO ₂ in order to acquire needed properties.
