ИСТИНА

Semiconductor quantum dots (QDs) are zero-dimentional objects, which deserved a particular attention due to their unique opticlal properties, high stability to the environment and high surface-to-volume ratio. The equally important factor is the possibility of the direct modification of QDs electronic and optical properties, using doping. Despite a large number of publications devoted to CdSe QDs, special attention is still focused on the doping problem. Here, we propose novel precoursors for the doping of CdSe QDs – AgCl and AgBr. In contrast to previous publications we realized doping directly during the colloidal synthesis of nanoparticles. As a precursor of Cd we used cadmium oleate, a precursor of selenium was tri-n-octylphosphine selenide (TOPSe) and silver halides were diluted in TOP to get solutions with different concentrations. Oleic acid serves as a stabilizer for colloidal synthesis
