New Findings from University of Notre Dame Update Understanding of Physical Chemistry (CdSe-Graphene Oxide Light-Harvesting Assembly: Size-Dependent Electron Transfer and Light Energy Conversion Aspects)

By a News Reporter-Staff News Editor at Biotech Week -- Researchers detail new data in Physical Chemistry. According to news originating from Notre Dame, Indiana, by NewsRx correspondents, research stated, "Excited-state interaction between CdSe quantum dots (QDs) of different sizes (2.3, 3.2, and 4.2 nm diameter) and graphene oxide (GO) was probed by depositing them as films on conducting glass electrodes."

Our news journalists obtained a quote from the research from the University of Notre Dame, "The emission of smaller CdSe QDs (2.3 nm) was quenched by GO three times faster than that of larger QDs (4.2 nm). Electrophoretic deposition allowed us to sequentially deposit single or multiple layers of different sized QDs and GO assemblies on conducting glass electrodes and to modulate the photoresponse in photoelectrochemical solar cells."

According to the news editors, the research concluded: "Superior photoconversion efficiency through the incorporation of GO was attributed to improved charge separation in the composite assembly."
