Abstract
Mesoporous TiO2 particles were prepared and characterized by X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM), which confirmed that well-organized mesostructure has been formed. Near-infrared absorbing tetra-amino manganese (II) phthalocyanine (TAMnPc) was synthesized and employed as sensitizer and TAMnPc sensitized mesoporous TiO2 (TAMnPc-TiO2) films were prepared and characterized by electronic absorption spectrum. Compared with bare TiO2 films, TAMnPc-TiO2 films exhibit an additional Q absorption band in near-infrared region. Current-voltage (I-V) characteristics of TAMnPc-TiO2 films in dark and under irradiation were tested. Adsorption of TAMnPc onto mesoporous TiO2 leads to a significant rise in photoconductivity.
