    Notes: Optical properties of gelatin with a very low concentration of silver particles were studied in the region from 300 to 800 nm. Such samples clearly showed isotropic properties and offered the advantage of having well-separated and noninteracting silver particles. Detailed optical constants for the gelatin matrix have been determined and their use, via the Mie theory, has enabled the determination of the dielectric constants and the loss function for the metallic particles themselves. An apparent blue shift in the plasma resonance absorption has been observed with the loss function when the particle size varied from 22 to 10 nm. Experimental data of this nature are needed for meaningful comparison between theory and experiment.

    Notes: A novel glassy ionic conductor, lithium niobium oxynitride, was prepared in form of thin films and characterized. Thin-film deposition was carried out by rf magnetron sputtering of LiNbO3 target in nitrogen-containing atmosphere. These films exhibit ionic conductivity of two orders higher than that of LiNbO3 films, the room-temperature conductivity being about 5×10−7 S cm−1. Film structure is highly cross linked, leading to activation energy as low as 0.5 eV. Film transmittance is higher than 85% in both the visible and solar ranges, making them also suitable for use in electrochromic devices. © 1996 American Institute of Physics.

    Notes: Optical and electrochemical properties of vanadium pentoxide (V2O5) films prepared by sol-gel method from organic and inorganic precursors were studied. The organic gel was obtained by hydrolysis and polycondensation of vanadium isopropoxide dissolved in isopropanol. The inorganic gel was prepared from aqueous solution of sodium vanadate. Lithium insertion in LiyV2O5 films (0〈y≤2.0) was investigated by cyclic voltammetry and electrochemical potential spectroscopy, showing good reversibility up to y∼2.0 and structure transitions from α phase to ε phase and δ phase in the range 0〈y≤1.0. Highest values for chemical diffusion coefficient were about 3×10−10 cm2/s at y∼0.8, as determined from complex impedance measurements. © 1996 American Institute of Physics.
