This study focuses on the fabrication and characterization of nanostructured zinc oxide films deposited glass substrates using sol–gel dip-coating methods. The thin are functionalized with silver ions at various Ag+ concentrations (10−2, 10−3, 10−4 M) through room temperature ion fixation process without ultraviolet (UV) illumination. Physicochemical techniques, such as employing Scanning Elect...
A series of SnO2-ZnO composite nanostructured (thin) films with different amounts of SnO2 (from 0 to 50 wt %) was prepared and deposited on a miniaturized porous alumina transducer using the sol-gel and dip coating method. The transducer, developed by our research group, contains Au interdigital electrodes on one side and a Pt heater on the other side. The sensing films were characterized using...
A Porous Nanostructured ZnO Layer for Ultraviolet Sensing with Quartz Crystal Microbalance Technique
Porous films of metals and metal oxides have gained growing attention as potential materials for use in applications that require large, specific surface areas, such sensors, supercapacitors, batteries. In this study, a “black-metal”-like porous Zn–ZnO composite layer was grown by room temperature co-sputtering Zn ZnO:Ga (3 at/%) ceramic targets. Following deposition, ZnO obtained subsequent th...
Adv. Mater. 2010, 22, 2329–2332 2010 WILEY-VCH Verlag G Since the advent of dye-sensitized solar cells (DSCs), which have achieved 11% of power conversion efficiency (PCE) in TiO2-based photoelectrodes, a lot of efforts have been devoted to make low-cost, light-weight, high-performance photovoltaic devices. Nanostructured metal oxides are one of key factors in determining the PCE of DSCs, becau...
