Electrochemical observation of a metal/insulator transition by scanning electrochemical microscopy
Article Abstract:
The novel use of the scanning electrochemical microscope to follow the compression of a monolayer of monodisperse silver thiol-capped nanoparticles on a Langmuir trough is presented. The result reveals that the transition from an insulating to conductive behavior with compression can be followed.

Large resonant stokes shift in CdS nanocrystals
Article Abstract:
The electronic spectrum of CdS colloidal quantum dots (QDs) with a radius of 1.0-2.3 nm was studied by low-temperature photoluminescence excitation spectroscopy. CdS QDs were found to exhibit a resonant Stokes shift of ~20-70 meV, which was ~4 times larger than similarly sized CdSe QDs.
