Electrochromic devices based on tungsten oxide

An electrochromic display is one of the most attractive candidates for paper-like displays, so called electronic paper, which will be the next generation display, owing to attributes such as thin and flexible materials, low-power consumption, and fast switching times.

Superior optical labels made from diamond nanoparticles

Optical labeling is an important tool in biological imaging because it offers superb discrimination between the sites of interest and the crowded background of a biological specimen. Diamonds nanocrystals have several advantages over other optical labels and open new opportunities in optical imaging, especially in applications where the size of optical labels represents an important parameter.

Quantum dots in a tube could open a new chapter in opto-electronics

Researchers in Germany managed to integrate quantum dots (QD) into the walls of nano- and microtubes. This novel structure serves as a quantum light emitter as well as optical waveguide. This represents a major step toward the realization of flexible high quality factor optical resonators based on tubes.
