[Investigation of the temperature-dependent spectral characteristics of colloidal PbSe nanocrystals].

In the present paper colloidal PbSe nanocrystals were prepared with the particle size of 3.8 and 5.8 nm, and the temperature- dependent optical properties of colloidal PbSe nanocrystals were investigated.

[Investigation of spectroscopy of ZnCuInS/ZnS quantum dots and poly-TPD].

In the present paper ZnCuInS/ZnS core/shell quantum dots were prepared with the particle size of 3.2 nm. Its radiation is based on the donoracceptor pair transitions, not the band edge emission.
