Paper Abstract

Large area photonic crystal has been fabricated with monodisperse silica spheres modified the surface with 3-(trimethoxysilyl) propylmethacrylate (TMSPM). The surface of the spheres has been modified by hydrolysis and condensation reaction of TMSPM with base catalyst and acid catalyst. The Fourier transform infrared (FTIR) spectra, field emission scanning electron microscope (FESEM) images no evidence that the TMSPM is corporate on the surface of the silica spheres for the base catalyst process. However, FTIR spectra and FESEM images clearly presents the existence of hydrolyzed TMSPM on the surface of silica spheres for the acid catalyst process. The FTIR absorption peak at 1714 cm-1 representing C=O stretching vibration indicates that the hydrolyzed TMSPM is corporate on the surface of the silica spheres. Although generally the colloidal photonic crystal has large number of cracks, surface modification and photocross-linking process during the packing process can be avoided the crack process of the photonic crystal.
