  • electron injection from colloidal pbs Quantum Dots into titanium dioxide nanoparticles
    ACS Nano, 2008
    Co-Authors: Byung-ryool Hyun, Adam C. Bartnik, Jason D. Goodreau, Thomas M Leslie, James R. Matthews, Yu-wu Zhong, Frank W Wise, Héctor D. Abruña, Nicholas F Borrelli
    Abstract:

    Injection of photoexcited electrons from colloidal PbS Quantum Dots into TiO2 nanoparticles is investigated. The electron affinity and ionization potential of PbS Quantum Dots, inferred from cyclic voltammetry measurements, show strong size dependence due to Quantum confinement. On the basis of the measured energy levels, photoexcited electrons should transfer efficiently from the Quantum Dots into TiO2 only for Quantum-dot diameter below ∼4.3 nm. Continuous-wave fluorescence spectra and fluorescence transients of PbS Quantum Dots coupled to titanium dioxide nanoparticles are consistent with electron transfer for small Quantum Dots. The measured electron transfer time is surprisingly slow (∼100 ns), and implications of this for future photovoltaics will be discussed. Initial results obtained from solar cells sensitized with PbS Quantum Dots are presented.

    Co-Authors: Byung-ryool Hyun, Adam C. Bartnik, Liangfeng Sun, Hector D. Abruña, Jason D. Goodreau, Thomas M Leslie, James R. Matthews, Yu-wu Zhong, Frank W Wise, Héctor D. Abruña, Nicholas F Borrelli
    Abstract:

    Injection of photoexcited electrons from colloidal PbS Quantum Dots into TiO(2) nanoparticles is investigated. The electron affinity and ionization potential of PbS Quantum Dots, inferred from cyclic voltammetry measurements, show strong size dependence due to Quantum confinement. On the basis of the measured energy levels, photoexcited electrons should transfer efficiently from the Quantum Dots into TiO(2) only for Quantum-dot diameter below approximately 4.3 nm. Continuous-wave fluorescence spectra and fluorescence transients of PbS Quantum Dots coupled to titanium dioxide nanoparticles are consistent with electron transfer for small Quantum Dots. The measured electron transfer time is surprisingly slow ( approximately 100 ns), and implications of this for future photovoltaics will be discussed.
