本文简要介绍了半导体纳米晶体量子点的合成、物理和光谱性质的研究以及应用分析。讨论了量子点的形态与其光谱特性之间的基本规律，以及一些理论模型，可以描述各种效应和过程：量子维效应，电子-声子相互作用，局域场效应，单量子点的光致发光闪烁。本文介绍了以CdSe为发光核的胶体量子点光谱随温度变化的实验和理论研究结果，阐明了单量子点及其系综光谱形成的本质
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
