Magnetic circular dichroism of CdTe nanoparticles

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.Magnetic circular dichroism (MCD) of water-soluble CdTe nanoparticles was observed in the visible spectral range for the first time. Diameter of nanoparticles varied from 2.3 to 4.5nm. Absorption and photoluminescence spectra were also recorded. Absorption line at 19400cm−1and luminescent line at 18200cm−1were observed. Splitting of value 960 cm−1was revealed in the MCD spectrum. Approximately the same splitting was extracted from the absorption spectrum. The MCD was identified as the temperature independent paramagnetic mixing effect. Nature of the absorption line and of its splitting are discussed
