Colloidal semiconductor nanocrystals (quantum dots, QD) manifest specific temperature dependent luminescence. Here we analyse temperature dependences of CdSe QD luminescence spectrum shift for different composites: polymers, glasses, crystals. The an

Here we present investigation of the thin film with CdSe nanocrystals with the size 2.3 nm made from low-concentration toluene solution. Using fluorescent microscopy method we have found small nanocrystals ensembles up to single nanocrystals. Lumines

Luminescence spectra of the colloidal solution of CdSe quantum dots (in toluene) were studied in a wide range of low temperatures. Samples were synthesized in the liquid crystal matrix of cadmium octanoate (CdC 8 ). A comparative analysis of the obta
