Fluorine-phosphate glasses doped with CdSe quantum dots were studied. As a result of glasses secondary heat-treatment, quantum dots were synthesized with sizes equal to 1.2-4.5 nm. Strong confinement was studied in two energy transitions (excited states of quantum dots) on photoluminescence excitation spectra. Experimental dependencies for the first and second energy transition on the nanoparticles size enable to conclude that no interaction occurs with fluorine-phosphate glass matrix and quantum dots.
