Description

Optical and microscopic characterization techniques performed synthesized nanoparticles A2B6 semiconductors. Optical and vibration properties were studied colloidal nanoparticles CdS (about 2 nm), stabilized in aqueous solutions small molecules, including tiohlikolevoyi and tiopropionovoyi acids in combination with hydrazine or ammonia molecules. The above examples NP characterized by a narrow size distribution, as evidenced by TEM and optical absorption spectroscopy and wide (spectral diapason) luminescence spectra in the range of quantum yield, reaching 50%. Demonstrated the possibility of resonance Raman spectroscopy on phonons in the diagnosis of structural and physical properties of semiconductor NCs and establishing the fundamental properties of low-dimensional systems.
