Photoconductivity of Reduced Graphene Films

Loomis J., Panchapakesan B., University of Louisville, US

In this paper, we report large photocurrents in air-assisted depositions of reduced graphene films (derived from reduced single layer graphene oxide) upon illumination with near-infrared (NIR) light. NIR-induced charge carrier generation and subsequent separation at [...]

Enhancement of photoelectrochemical and optical characteristics using a TiO2 nanoparticles interlayer in MEH-PPV heterojunction devices

Habelhames F., Girtan M., Manole A., Lamiri L., Zerguine W., Nessark B., Univesité Ferhat Abbas, DZ

In this work, MEH-PPV+TiO2 composite material was prepared by incorporation of titanium oxide nonoparticles (TiO2) into poly[2-methoxy-5-(2'-ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) polymer matrix and deposited by spin coating on glass and indium thin oxide (ITO) substrates. The absorbance [...]

Synthesis and Characterization of Anodized Titanium Oxide Nanotubes Arrays

Hu M.Z., Lai P., Bhuiyan M.S., Tsouris C., Gu B., Paranthaman M.P., Gabitto J., Prairie View A&M University, US

Anodized titanium oxide containing highly ordered, vertically oriented TiO2 nanotube arrays is a nanomaterial architecture that shows promise for diverse applications. In this paper, an anodization synthesis using HF-free aqueous solutions is described. The anodized [...]
