  • Group II alloyed I-III-VI semiconductor nanocrystal compositions and methods of making same
    Patent number: 8409473
    Abstract: A semiconductor nanocrystal composition that is stable and has high luminescent quantum yield. The semiconductor nanocrystal composition has a semiconductor nanocrystal core of a group II alloyed I-III-VI semiconductor nanocrystal material. A method of making a semiconductor nanocrystal composition is also provides which includes synthesizing a semiconductor nanocrystal core of a group II alloyed I-III-VI semiconductor material.

  • LOW COST AND HIGH YIELD METHOD OF MAKING LARGE QUANTITY AND HOMOGENOUS METAL NANOPARTICLES AND CONTROLLING THEIR SOLUBILITY
    Publication number: 20110218304
    Abstract: The present invention is directed to a low cost and high yield synthetic method of producing large quantity and homogenous metal nanoparticles, which are capped by both hydrophilic and hydrophobic surfactants and soluble in water, water-miscible solvents, and non-polar solvents. The solubility of metal nanoparticles in different solvents can be controlled by simply changing the ratio of hydrophilic and hydrophobic surfactants.

  • COMPOSITION FOR MAKING TRANSPARENT CONDUCTIVE COATING BASED ON NANOPARTICLE DISPERSION
    Publication number: 20110193032
    Abstract: The present invention is directed to a composition for preparing transparent conductive coating on transparent substrate by an environment friendly method. An aqueous foam dispersion containing metal nanoparticles can form a transparent film by spontaneous self-assembly, which becomes conductive after sintering. The foam formulation contains mainly water without any toxic organic solvent.
