  • Patent number: 9290671
    Abstract: Electronic printing devices ink has nanoparticles of semiconducting materials with desired composition, size and band gap and modified with a volatile capping agent. Mercury cadmium telluride is synthesized by refluxing a mixture of metal salt and telluride precursor. Mercury (II) acetate and cadmium (II) acetate are reacted with a tellurium precursor (e.g. tri-n-octylphosphine telluride or telluric acid) in presence of a ligand (e.g. 1-dodecanethiol or oleylamine). This protocol yields nanoparticles of diameter ˜2-1000 nm range. The desired composition of nanoparticles is obtained by varying the relative concentration of the metal precursor. The ink is formulated by modifying the nanoparticles with volatile capping agent and dispersing the modified nanoparticles in a solvent.
