Paper Abstract

In the present paper we analyze peculiarities of CdSe/ZnS colloidal quantum dots (QDs) nonlinear optical properties due to the one- and two-photon excitation of basic electron-hole (exciton) transition by means of ultra-short laser pulses. We also revealed the main mechanisms of optical nonlinearities which result in the laser beam divergency. To find out the role of quantum dots, two different types of solvents were investigated - toluene or hexane based colloidal solutions.
