Photodynamic effects in nanocomposites based on quantum dots of cadmium sulfide embedded in a silicate matrix, in their interaction with the laser beam

摘要

In this paper we study the possibility of modifying the optical properties of nanocomposites based on CdS quantum dots embedded in a silicate matrix, in their interaction with the laser radiation. It was found that the action of laser radiation leads to local change in the refractive index of the nanocomposite, the dynamics of which depends on the exposure conditions..
