N2 - The semiconductor CdSe quantum dots (QDs) with emission spectra of different wavelengths were synthetized by using a modified method of simultaneous injection at heating. The obtained QDs were encapsulated into liposomes prepared by a method of lipid film hydration and sonication from various phospholipid compositions and polyethylene glycol (PEG) addition. The synthesized and encapsulated in the liposomes QDs were characterized by photoluminescence (PL), X-Ray diffraction (XRD), Transmission electron microscopy, and Dynamic light scattering. The evaluation of PL spectra of the obtained QDs showed that they had sizes in the range of 2.3–4.5 nm. XRD patterns revealed only one peak for CdSe cubic crystal structure and the estimated crystal sizes were about the same values that the obtained from PL results. After the encapsulation a blue shift of PL peak position was observed. The mechanism of the effect is discussed.
