Photonic crystals based on two-layer opaline heterostructures

2002

AbstractOptical properties of several heterostructures representing two-layer opaline photonic crystals have been examined. Two separate stop-bands have been observed both in transmission and emission spectra. The effect of the interface disorder on the optical spectra was not observed, probably, due to the insufficient degree of order of the opaline layers.

Large Photonic Films by Crystallization on Fluid Substrates

2002

Cracks, which appear due to shrinkage during drying of artificial opaline films, strongly limit the use of these materials. Crystallization on fluid substrates (liquid metals) is a way to circumvent this problem. By this method it is possible to prepare crack-free three-dimensional “monocrystals” with a very low defect density and the size in millimeters.
