Provided herein are novel ink formulations based on metal salts and metal complexes.

Inks containing metal precursors nanoparticles

Provided are novel ink formulations based on metal salts and metal complexes. The formulations include a sole metal precursor in the form of metal salt nanoparticles dispersed in a medium. In addition, the metal salt nanoparticles may include an anion. The novel ink formulations may be used for producing conducting patterns.

Provided is a composition including a plurality of multi-metallic nanoparticles each consisting essentially of a core including at least one first metal (Me1) and a continuous shell including atoms of at least one second metal (Me2). Optionally, the continuous shell of Me2 atoms protects the Me1 atoms from oxidation at all temperatures less than 150&#xb0; C.

Core-shell metallic nanoparticles, methods of production thereof, and ink compositions containing same

The invention provides processes for the manufacture of conductive transparent films and electronic or optoelectronic devices comprising same.

Transparent conductive coatings for optoelectronic and electronic devices

The invention relates to a method for preparing an aqueous-based dispersion of metal nanoparticles comprising: (a) providing an aqueous suspension of a metal salt; (b) pre-reducing the metal salt suspension by a water soluble polymer capable of metal reduction to form a metal nuclei; and (c) adding a chemical reducer to form metal nanoparticles in dispersion. The invention further relates to aqueous-based dispersions of metal nanoparticles, and to compositions such as ink comprising such dispersions.
