Optical properties of polyelectrolyte quantum dot multilayer films prepared using the layer by layer self-assembly method
Lioudakis, Emmanouil E.; Koupanou, E.; Kanari, C.; Leontidis, Epameinondas; Othonos, Andreas S. (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 ...

Stabilization of lead sulfide nanoparticles by polyamines in aqueous solutions. A structural study of the dispersions
Koupanou, E.; Ahualli, S.; Glatter, O.; Delgado, A.; Krumeich, F.; Leontidis, Epameinondas (2010)Lead sulfide (PbS) nanoparticles have been synthesized in aqueous solutions by a reaction between inorganic lead salts and sodium sulfide and stabilized using the cationic polyelectrolytes branched poly(ethylenimine) (PEI), ...
