Influence of transition metal alloying and surface modification of the CdTe quantum dots on their optical properties, band structure and electrochemical activity
We report a study of CdTe quantum dots modification by the alloying of with Zn2+ and Hg2+ ions and shell growth. Optical and cyclic voltammetry measurements were used to explain changes in the band structure of the particles via shell growth and during the alloying. Influence of stabilizer on the electrochemical behavior of the particles is also discussed. Obtained nanostructures demonstrate photoluminescence in the wider range of wavelengths than pure CdTe QDs.
