    Abstract: Improved silicon/germanium nanoparticle inks are described that have silicon/ germanium nanoparticles well distributed within a stable dispersion. In particular the inks are formulated with a centrifugation step to remove contaminants as well as less well dispersed portions of the dispersion. A sonication step can be used after the centrifugation, which is observed to result in a synergistic improvement to the quality of some of the inks. The silicon/germanium ink properties can be engineered for particular deposition applications, such as spin coating or screen printing. Appropriate processing methods are described to provide flexibility for ink designs without surface modifying the silicon/germanium nanoparticles. The silicon/germanium nanoparticles are well suited for forming semiconductor components, such as components for thin film transistors or solar cell contacts.

    Abstract: Small particles provide for improved performance as phosphors especially in the production of display devices. Particles with an diameter less than about 100 nm have altered band properties that affect the emission by the particles. A collection of such small particles with a narrow distribution around a selected average diameter can be used to produce emission at a desired frequency. These particles are effective for producing a wide variety of display types including flat panel displays. Laser pyrolysis provides an efficient process for the production of desired particles.

    Abstract: Improved batteries described herein generally comprise an electrolyte having lithium ions and a cathode comprising submicron metal vanadium oxide particles. In some embodiments, the battery demonstrate an accessible curren t capacity of a least about 220 mAh/g when pulsed in groups of four constant energy pulses at a current density of 30 mA/cm2 to deliver 50 Joules per pulse. The four pulses of a pulse train are separated by 15 seconds of rest between each pulse, and there are 6 days between pulse groups, upon discharg e down to a pulse discharge voltage of 2 V. In further embodiments, the batteries have an average internal electrical resistance of no more than 0.2 Ohms at a current density of at least about 30 mA/cm2. Furthermore, the batteries can have a current capability of at least about 0.4 amps per cubic centimeter battery volume. Due to the improved discharge performance, the batteries can exhibit no significant voltage delay throughout the life of th e battery as demonstrated in a three month accelerated discharge test.
