UV tuning of cadmium telluride quantum dots (CdTe) - assessed by spectroscopy and electrochemistry
Original language description
In this work the electrochemical analysis (potentiometric stripping analysis - PSA, cyclic voltammetry - CV) and evaluation of fluorescence properties of CdTe - QDs were performed. Using CV it was found that average value of AE of QDs is lower than 0.059V and I is in direct correlation with square root of scan rates, therefore we assume that this system represents rather reversible than quasi-reversible process. Further, it was found that nearly 1.4 electrons are exchanged in both cases, which corresponded with expected electron transfer. Fluorescence analysis showed that UV radiation (254 and 312 nm) sig-nificantly changes fluorescence properties of CdTe in time 0 - 60 min. It was found that after 5 min of UV irradiation (X = 312 nm) the fluorescenceintensity increased by 37% and at X=254 nm the increase in fluorescence intensity was even bigger, by 45% (compared to the cont-rol without irradiation). UV radiation also caused a shift in the emission maximum of CdTe - QDs by approxima
