AB  - We have synthesized CdS and Cd0.7Mn0.3S nanocrystals with diameters of about 4.5 nm. These materials have been studied using photoluminescence spectroscopy with various excitation energies in the temperature range from 1.8 to 300 K, in magnetic field up to 5T. We registered surface and defect states as well as two Mn2+ energy levels that correspond to Mn2+ ions in two different crystal environments. We proposed the scheme of energy levels and transitions that explain obtained experimental results. (C) 2012 Elsevier B. V. All rights reserved.

AB  - The nanocomposite consisting of PbS quantum dots with average diameter of 26 A and polyvinyl alcohol was characterized using photoluminescence and far-infrared spectroscopy. Photoluminescence spectra of nanocomposite, measured in temperature range from 8 to 280 K, consists of broad peak which spans the energy range from 1.2 to 2.1 eV and can be connected with trap states inside the band gap. Far-infrared measurements are consistent with theoretical calculations that include mechanical boundary conditions at the quantum dot - host interface. Observed peak at 90 cm(-1) can be assigned to coupled modes with l(p) = 1, while broad peak at 275 cm(-1) is above any lattice frequency and is close to sum of the frequencies of the l(p) = 0 acoustic and l(p) = 0 coupled optical mode of PbS quantum dots.
