Paper Abstract

We investigate quantum dots (QDs) of ternary compounds CdXHg1-XSe with 0<X<1 using a Raman scattering technique at room temperature. We obtained the correlation between QDs chemical composition and the frequencies of CdSe-like LO and the HgSe-like TO and LO modes. It is shown that the crystalline structure of original CdSe QDs used for Cd/Hg substitution, either zinc blende or wurtzite affects strongly on structural properties of resultant CdXHg1-XSequantum dots.
