Transient Optical Studies of Interfacial Charge Transfer at Nanostructured Metal Oxide/PbS Quantum Dot/Organic Hole Conductor Heterojunctions

Posted on February 8, 2010 at 12:45am 0 Comments

We report a transient absorption and luminescence study addressing the charge separation, recombination, and regeneration reactions at nanostructured metal oxide/PbS quantum dot/organic hole conductor

heterojunctions. We show that yields of charge separation are

significantly higher at PbS/SnO2 interfaces relative to PbS/TiO222. We also report a correlation between the PbS particle size and the…

A greener route to photoelectrochemical PbS nanoparticles

Posted on February 8, 2010 at 12:38am 0 Comments

A cheap and more environmentally friendly method for the synthesis of

high quality PbS nanoparticles in olive oil at 60 °C has been

developed. Carefully controlling the conditions of reactions leads to

PbS nanoparticles with well-defined sizes, and band gaps between 1.72

and 0.88 eV. The nanoparticles were characterized by XRD, HRTEM, NIR

absorption spectroscopy, X-ray photoelectron spectroscopy (XPS) and a

fluorescence lifetime experiment based on…

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
