Anti-stokes cooling in semiconductor nanocrystal quantum dots : a feasibility study

摘要

In this review, we discuss the feasibility of laser cooling ofsemiconductor nanocrystal quantum dots by phonon-assistedanti-Stokes photoluminescence. Taking into account recentexperimental advances, in particular, the development ofsemiconductor nanocrystals with very high quantum yield, we analyze in detail how the various physical processes innanocrystals might help or hinder the cooling process. Possibleexperimental approaches to achieve efficient optical cooling arealso discussed.
