Title: Silica nano-spheres prepared by modified Stober process for colloidal crystal growth
Abstract: Colloidal crystals are closely related to photonic crystals as both of them can be considered as composite materials with a spatial distribution of building blocks. The first step in fabricating such a crystal is the development of highly monodisperse spherical nanomaterials. In this work silica nanoparticles with fine spherical shapes were prepared by following a seeded growth method. The effect of different fabrication conditions on the shape and monodispersity of the prepared spheres were analyzed with the help of scanning electron microscopy and dynamic light scattering systems. The use of the prepared sample for colloidal crystal growth is analyzed using UV-Vis spectra.
