Quantum dots CdSe deserve a particular attention due to their unique optical properties, high stability against the internal influence, and possibility of simple control over the shape and size of such nanocrystals. Colloidal method of synthesis is widely used in practice, and it allows to modify practically any parameters of nanoparticles. Here we propose the investigation of CdSe quantum dots which were synthesized in the presence of silver halides (halides = chloride, bromide and iodide). To understand a process of nanoparticle formation in more detail we varied the silver halide amount in synthesis and proposed a sampling during colloidal growth. The attempts were focused on the investigation of shape and optical properties of nanoparticles.
