Nanocomposites Based on CdS Quantum Dots for Laser Control Devices

Abstract:

Here we report about study the novel class of nanocomposite for optical control devices. It was observed that nanocomposite based on cadmium sulfide quantum dots in silica matrix can change its optical properties under irradiation of UV-light. These changes are expressed as increasing of optical absorbance coefficient and not only decreasing of luminescence intensity but in some cases red-shifting of maximum. Dependence of quantum dot optical properties upon the kind of matrix and polarization degree of modifying radiation was obtained.
