摘要：

We present a theoretical scheme for laser cooling of the colloidal cadmium selenide (CbSe) QDs. The laser cooling process is based on the anti-Stokes fluorescence observed in QDs. We have considered laser cooling in the system of identical CdSe QDs laser pumped with energy of photons less than mean fluorescence energy. The dependences of all parameters of the system on the temperature have been taken into account. Following to our simulation the laser cooling with temperature drop similar to 100K can be realised with well technologically developed today passivated CdSe QDs.
