"Somewhere over the rainbow"

Description

The image shows the whole field of view of a graphene oxide (GO) doped sample of CE8 in the fluid smectic phase. The sample was prepared between a microscope slide and a cover slip at a temperature of 128ºC. Smectic fans are arranged in a quasi-circular, flower-like fashion and the coverage of all colours of the visible spectrum from bottom left to top right, is due to a slight wedge-shaped arrangement of the cover slip. The image was taken with a 4x objective on a Leica DMLP polarizing microscope, equipped with a Linkham hot stage and a UEye digital camera. It has not been digitally enhanced by any means and the droplet diameter is equivalent to 2.5 mm. The texture microphotograph was taken during an internship at the University of Manchester with the Liquid Crystals group under supervision of Dr. Ingo Dierking.
