Abstract

The shift of photonic bandgap could be used to study the adsorption behavior of concentration. However, there are so many issues need to explore in this field, such as adsorption models and influence factors. In this paper, it is found that the size of initial particles has a great impact on the size of silica colloidal spheres and the volume fraction of pore, resulting in the different adsorption behavior on the surface of silica photonic crystals. The effect of initial particle size on colloidal spheres and volume fraction of pore are investigated. Furthermore, the effect of initial particle size on gas adsorption behavior has been discussed by using the volume fraction of adsorption vapor (Vvap). It can be seen that the trends of isopropanol adsorption differ from methanol and ethanol.
