MSU scientists have developed a smart liquid crystals doped quantum dots

MSU scientists have developed a "smart" liquid crystals with the addition of quantum dots — reported Online MSU. The study is published in Advanced Materials. On liquid crystals can be developed with ultraviolet light to record an image, and then read this information — scanning the liquid crystal in the same ultraviolet light and capturing changes in the degree of polarization of the light emitted by the material. Liquid crystals with similar properties are of interest as potential device for recording, storing and reproduction of image information.

Short memory shimmering quantum dots

Researchers from the Institute of Physics of PN Lebedev and his colleagues have made the next step to understanding the nature of the shimmering luminescence of quantum dots. They found that semiconductor nanocrystals CdSe / CdS have a certain memory effect — the last state of the system affect the evolution of its fluorescence. The data obtained will help to find ways to control flickering fluorescent, unpredictable nature of which still limits the perspectives of nanodots.

Russian scientists have created a nanocomposite is controlled by light

A team of scientists from Moscow State University of Fine Chemical Technology. MV Lomonosov, Institute of Biochemical Physics. NM Emanuel Academy of Sciences, Institute of Problems of Chemical Physics, Russian Academy of Sciences, taking as a basis the photochromic ligands and cadmium selenide, synthesized composite whose properties can be changed by irradiation with light of a specific wavelength. The resulting hybrid material can be used in photocontrollable "smart" devices.

Purposeful change in the properties of photochromic materials by light exposure — an extremely popular area of research. As a general rule, the successful results of such work are the basis
