Improved triplet state parameters for indium octacarboxy phthalocyanines when conjugated to quantum dots and magnetite nanoparticles
C Tshangana, T Nyokong - Journal of Molecular Structure, 2015 - Elsevier
Fe 3 O 4 magnetic nanoparticles (MNPs) and glutathione (GSH) capped CdSe@ ZnS
quantum dots (QDs) were separately coordinated to indium octacarboxy phthalocyanine
(InPc (COOH) 8) to form ClInPc (COOH) 8–MNPs and ClInPc (COOH) 8–GSH–CdSe@ ZnS,
respectively. The photophysical parameters (triplet state and fluorescence quantum yields
and lifetimes) were determined for the conjugates. The triplet quantum yields increased from
Φ T= 0.49 for InPc (COOH) 8 alone to Φ T= 0.61 and 0.56 for InPc (COOH) 8 in the …
