Down-converting lanthanide doped TiO2 photoelectrodes for efficiency enhancement of dye-sensitized solar cells

Down-converting lanthanide doped TiO2 photoelectrodes for efficiency enhancement of dye-sensitized solar cells: "Publication year: 2011

H., Hafez , M., Saif , M.S.A., Abdel-Mottaleb
Lanthanide (Ln3+) doped TiO2 down-conversion photoelectrodes (Ln3+=Eu3+ and Sm3+ ions) are used to enhance the photovoltaic efficiency of dye-sensitized solar cells (DSSC). We report on achieving fill factors of 0.67 and 0.69 and efficiencies of 5.81% and 5.16% for Sm3+ and Eu3+ respectively. This is compared to the 4.23% efficiency for the undoped-titania photoelectrodes. This enhancement is probably due to the improved UV radiation harvesting via a down-conversion luminescence process by the lanthanide ions. The ?structure, optical and photoluminescence properties of the down-converting photoelectrode are characterized by X-ray diffraction? (?XRD?),? scanning electron microscope (SEM), energy dispersive X-ray (EDX) and room..."

Jingjing, Du , Chuanyong, Jing
A novel sensitive and recyclable SERS substrate which can actively concentrate chromate (Cr(VI)) in water and substantially enhance Raman signal was synthesized as uniform Fe3O4@Ag nanoparticles. The surface morphology, structure, and magnetic properties were characterized using transmission electron microscopy, atomic force microscopy, X-ray powder diffraction, X-ray photoelectron spectroscopy, and vibrating sample magnetometry analysis. The closely spaced Fe3O4@Ag substrate with a core-shell structure exhibited a 25 nm surface roughness. The high saturation magnetization at 48.35 emu g-1 enabled the complete and rapid separation of the substrate from the solution. The sensitivity and reproducibility of the substrate were confirmed using a common...

Graphical abstract

Graphical abstract: The synthesized Fe3O4@Ag nanoparticles with an average of 27 nm particle size and 25 nm surface roughness could be used as active SERS substrates for Cr(VI) determination. Research highlights: ► A simple process was introduced to synthesize Fe3O4@Ag magnetic nanostructures as SERS substrates. ► The SERS substrate can actively adsorb and concentrate Cr(VI) in water and substantially enhance Raman signal. ► Qualitative and quantitative determination of Cr(VI) was achieved using a portable Raman spectrometer, which provided a potential technique for in-situ Cr(VI) determination.
