The article provides a brief overview of the works devoted to the synthesis, study of photophysical and spectral properties and analysis of applications of semiconductor nanocrystals – ​quantum dots. The fundamental laws connecting the morphology of quantum dots with its optical-­spectral characteristics are discussed, as well as some theoretical models that allow describing various effects and processes: the quantum-­dimensional effect, electron-­phonon interaction, local field effects, photoluminescence blinking of single quantum dots. The results of original experimental and theoretical studies of the temperature dependences of the spectra of colloidal quantum dots with a CdSe emitting core are presented, which made it possible to clarify the nature of the formation of the spectra of single quantum dots and their ensembles.
