Optical properties of polyelectrolyte quantum dot multilayer films prepared using the layer by layer self-assembly method
(2008)In this work, we have used spectroscopic ellipsometry to study the optical properties of polyelectrolyte-PbS quantum dot (QD) multilayer films prepared using the layer by layer self-assembly method. The optical results ...

Size-dependent charge transfer in blends of Pbs quantum dots with a low-gap silicon-bridged copolymer
(2013)The photophysics of bulk heterojunctions of a high-performance, low-gap silicon-bridged dithiophene polymer with oleic acid capped PbS quantum dots (QDs) are studied to assess the material potential for light harvesting ...

Sn:In2O3 and Sn:In2O3/NiS2 Core-Shell Nanowires on Ni, Mo Foils and C Fibers for H2 and O2 Generation
(2017)Sn:In2O3 nanowires have been grown by the vapor liquid solid mechanism on Si, Ni, Mo, and C fibers. These were used to obtain Sn:In2O3/NiS2 core-shell nanowires by the deposition of 10 nm Ni over the Sn:In2O3 nanowires ...

Surface-related states in oxidized silicon nanocrystals enhance carrier relaxation and inhibit auger recombination
(2008)We have studied ultrafast carrier dynamics in oxidized silicon nanocrystals (NCs) and the role that surface-related states play in the various relaxation mechanisms over a broad range of photon excitation energy corresponding ...
