【 摘 要 】

Titania (TiO2) coated polystyrene (PS) (PS/TiO2 core-shell) colloids were prepared by sol–gel process and self-assembled into photonic crystals through the vertical deposition method. The PS/TiO2 core-shell colloidal particles were characterised using SEM, laser particle size analyser, FTIR and EDS. The results show that the colour is shifted gradually from blue to red with the increase of titania shell thickness which changes both the particle size and the contrast index.
