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 the time-correlated single
photon counting (TCSPC) technique. Photoelectrochemical study carried
out by steady-state current–voltage measurements of self-assembled PbS
nanoparticles on ZnO–SnO2 in electrodes in 1 M Na2SO3 electrolyte solution showed that as-prepared PbS nanoparticles were photochemically active.
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 email@example.com
