Data on Nanocrystals Reported by Researchers at Hebrew University (A General Strategy for Synthesizing Colloidal Semiconductor Zinc Chalcogenide Quantum Rods)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Fresh data on Nanocrystals are presented in a new report. According to news reporting out of Jerusalem, Israel, by VerticalNews editors, research stated, "Quasi-one-dimensional (1D) semiconductor nanocrystals manifest linearly polarized emission, reduced lasing threshold, and improved charge transport compared with their counterparts such as spherical quantum dots. Present investigations of colloidal semiconductor quantum rods are mainly based on cadmium chalcogenide systems because of their facile synthetic accessibility."

Our news journalists obtained a quote from the research from Hebrew University, "However, it is still a big challenge to fabricate quasi-1D zinc chalcogenide nanocrystals with controlled aspect ratios. Here we report a general strategy for synthesizing zinc chalcogenide quantum rods via a colloidal chemical synthetic approach. Unlike the most common growth mechanisms of quasi-1D colloidal nanocrystals such as monomer attachment and particle coalescence, the synthesis of zinc chalcogenide quantum rods is performed by a ripening process starting from their respective ultrathin nanowires through thermodynamically driven material diffusion. We anticipate that this strategy is general and could be applied to other systems to construct quasi-1D nanostructures."

According to the news editors, the research concluded: "Moreover, the presence of cadmium-free (or 'green') zinc chalcogenide quantum rods synthesized through this strategy provides a desirable platform for eco-friendly photocatalysis, optoelectronic devices, biolabeling, and other applications."
