Photoconductivity Enhancement in Multilayers of CdSe and CdTe Quantum Dots
ACS Nano, 2011Charge separation at the interface between CdSe and CdTe quantum dots was investigated by comparing the photoconductivity of films consisting of only CdSe or CdTe quantum dots to that of films with alternating layers of CdSe and CdTe quantum dots. The photoconductivity for alternating layers is three times higher than for the single component layers ...

Interaction of porphyrins with CdTe quantum dots
Nanotechnology, 2011Porphyrins may be used as photosensitizers for photodynamic therapy, photocatalysts for organic pollutant dissociation, agents for medical imaging and diagnostics, applications in luminescence and electronics. The detection of porphyrins is significantly important and here the interaction of protoporphyrin-IX (PPIX) with CdTe quantum dots was studied ...

Quantized Growth of CdTe Quantum Dots; Observation of Magic-Sized CdTe Quantum Dots
The Journal of Physical Chemistry C, 2007This work presents experimental observation of the quantized growth of CdTe quantum dots (QD) in the presence of hexadecylamine (HDA), hexylphosphonic acid (HPA), and trioctylphosphine oxide (TOPO) above 200 °C. The crystal growth of CdTe QDs is monitored by in situ UV−vis absorption spectroscopy.

MRS Proceedings, 2009
AbstractQuantum dots (QDs) are fluorescent semiconductor (e.g. II-VI) nanocrystals, which have a strong characteristic spectral emission. This emission is tunable to a desired energy by selecting variable particle size, size distribution and composition of the nanocrystals. QDs have recently attracted enormous interest due to their unique photophysical

Conjugating Luminescent CdTe Quantum Dots with Biomolecules
The Journal of Physical Chemistry B, 2008Newly prepared CdTe quantum dots ( QD) bearing shells of water solubility providing capping agents (i.e., thioglycolic acid ( TGA) and 2-(dimethylamino)ethanethiol hydrochloride (DMAET) were subjected to electrostatic assays with several proteins (i.e., cytochrome c (cyt c) and human serum albumin (HSA). In particular, we employed absorption, emission,
