Photo-oxidation-enhanced coupling in densely packed CdSe quantum-dot films
نویسندگان
چکیده
Photo-oxidation of densely packed monolayer of CdSe quantum dots ~QDs! was studied by time-resolved photoluminescence ~PL! spectroscopy. Electrons yielded in QDs by the strong laser-pulse irradiation can assist the oxidation of CdSe QDs. Such rapid photo-oxidation does not introduce more nonradiative defects, instead, it enhances the coupling between QDs through surface modification and the PL intensity can be significantly improved. © 2003 American Institute of Physics. @DOI: 10.1063/1.1590735#

Anomalous photo-induced spectral changes in CdSe=ZnS quantum dots
We study photo-induced static and dynamic spectral changes in self-assembled CdSe=ZnS quantum dot (QD) thin films with varying QD concentrations under ambient conditions. Using spatially resolved scanning photoluminescence microscopy in conjunction with spectrally resolved time-correlated photon counting, we measure the variations in spectral intensity, emission wavelength, and recombination li...
متن کاملControlling photo-induced spectral changes in CdSe/ZnS quantum dots by tuning inter-dot energy transfer
We study photo-induced spectral changes in films containing two sizes of chemically synthesized CdSe/ZnS quantum dots (QDs) using static and time-resolved spectroscopies. As the concentration of the smaller (donor) QDs is varied over two orders of magnitude relative to the larger (acceptor) dots, we find that with decreasing proportion of donors, the photo-oxidation rate increases in acceptors ...

We demonstrate a low cost, phosphine-free route to synthesize CdSe quantum dots (QDs) by heating the mixed precursors of Se and Cd up to 260 C. The as-synthesized CdSe QDs are characterized by using UV-visible absorption spectroscopy, high resolution transmission electron microscopy, X-ray diffractrometry, and EDX analyses. The CdSe QDsensitized TiO2 films of solar cells has been fabricated by ...
متن کاملThe Effect of pH on the Optical Band Gap of PbSe Thin Film with Usability in the Quantum Dot Solar Cell and Photocatalytic Activity
This study was an attempt to provide a simple solution processed synthesis route for Lead Selenide (PbSe) nanostructure thin films using the chemical bath deposition (CBD) method which is commercially available in inexpensive precursors. In the CBD method, the preparation parameters play a considerable role and determine the nature of the final product formed. Known as two main factors, the eff...
