Abstract :
The optical stop band in the transmission spectrum and the diffraction peak in the reflection spectrum of opals with a three-dimensionally periodic structure shift markedly by the infiltration with various liquids and liquid crystals. Utilizing these phenomena, a new simple method to evaluate the refractive index of liquids and liquid crystals have been proposed
