TL;DR: In this paper, a growth technique of the semiconductor microcrystals in a glassy dielectric matrix has been developed, which permits to vary the size of the grown microcrystal in a controlled manner from some tens to thousands of angstroms.

TL;DR: The formation of atomically flat quasi-two-dimensional colloidal CdSe, CdS and CdTe nanoplatelets with well-defined thicknesses ranging from 4 to 11 monolayers with electronic properties of two-dimensional quantum wells formed by molecular beam epitaxy are demonstrated.

TL;DR: In this article, the authors proposed a model in which the time dependence of the photoluminescence intensity of a single nanosize quantum dot under cw excitation conditions shows a sequence of ''on'' and ''off'' periods similar to a random telegraph signal.

TL;DR: In this article, the authors have studied theoretically electron spin relaxation in semiconductor quantum dots via interaction with nuclear spins and showed that the relaxation is determined by three processes: (i) the precession of the electron spin in the hyperfine field of the frozen fluctuation of the nuclear spins; (ii) the spin precession in the dipole field of its nuclear neighbors.

TL;DR: The band edge exciton structure is calculated, including the effects of the electron-hole exchange interaction and a nonspherical shape, in CdSe quantum dots to show the importance of exciton spin dynamics in the recombination mechanism.
