Fluorescence quantum efficiency of CdSe/ZnS quantum dots functionalized with amine or carboxyl groups

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) confi...

520			\|a 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 $ λ_{p} $ = 632.8 nm was used as the probe beam, and an $ Ar^{+} $ laser (at $ λ_{e} $ = 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–$ NH_{2} $) or carboxyl (R–COOH) groups. The average values of the thermal diffusivity D = (1.48 ± 0.06) × $ 10^{−3} $ $ cm^{2} $/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.

TL transient measurements were performed using the mode-mismatched dual-beam (excitation and probe) configuration. A He–Ne laser at $ λ_{p} $ = 632.8 nm was used as the probe beam, and an $ Ar^{+} $ laser (at $ λ_{e} $ = 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–$ NH_{2} $) or carboxyl (R–COOH) groups. The average values of the thermal diffusivity D = (1.48 ± 0.06) × $ 10^{−3} $ $ cm^{2} $/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.

TL transient measurements were performed using the mode-mismatched dual-beam (excitation and probe) configuration. A He–Ne laser at $ λ_{p} $ = 632.8 nm was used as the probe beam, and an $ Ar^{+} $ laser (at $ λ_{e} $ = 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–$ NH_{2} $) or carboxyl (R–COOH) groups. The average values of the thermal diffusivity D = (1.48 ± 0.06) × $ 10^{−3} $ $ cm^{2} $/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.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CdSe/ZnS core–shell nanoparticles</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Thermal lens</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Thermo-optical parameters</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Radiative quantum efficiency</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Quantum dots functionalized</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Munin, Egberto</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of nanoparticle research</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V, 1999</subfield><subfield code="g">14(2012), 10 vom: 08.

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 $ λ_{p} $ = 632.8 nm was used as the probe beam, and an $ Ar^{+} $ laser (at $ λ_{e} $ = 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–$ NH_{2} $) or carboxyl (R–COOH) groups. The average values of the thermal diffusivity D = (1.48 ± 0.06) × $ 10^{−3} $ $ cm^{2} $/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.
