Fluorescence quantum efficiency of CdSe/ZnS quantum dots functionalized with amine or carboxyl groups
Source abstract
Abstract
The thermo-optical parameters of cadmium selenide/zinc sulfide (CdSe/ZnS) core–shell quantum dots (QDs) suspended in aqueous solutions were measured using a Thermal Lens (TL) technique. TL transient measurements were performed using the mode-mismatched dual-beam (excitation and probe) configuration. A He–Ne laser at λp = 632.8 nm was used as the probe beam, and an Ar+ laser (at λe = 514.5 nm) was used as the excitation beam to study the effect of the core sizes (2–4 nm) of CdSe/ZnS nanocrystals functionalized with amine (R–NH2) or carboxyl (R–COOH) groups. The average values of the thermal diffusivity D = (1.48 ± 0.06) × 10−3 cm2/s obtained for QDs samples are in good agreement with the pure water solvent result. The fraction thermal load (φ) and radiative quantum efficiencies (η) of the functionalized CdSe/ZnS QDs were determined and compared with non-functionalized CdSe/ZnS QDs. The obtained η values for non-functionalized CdSe/ZnS are slightly higher than those for the QDs functionalized with amine or carboxyl groups.
