ZnIn2S4 nanotubes and nanowires have been selectively fabricated via a convenient one-step wet-chemical approach by using porous polycarbonate membrane as a hard template. The wall of nanotubes is as thin as 5 nm, and the diameter of them is 200 nm. Formation mechanism of ZnIn2S4 nanotubes and nanowires is also discussed according to the experimental results. The structure, morphology, and composition properties of the as-prepared samples were characterized using X-ray powder diffraction, UV-vis spectrophotometer, transmission electron microscopy, energy dispersive X-ray spectrometry, and scanning electron microscopy.
GeSe single‐crystalline microtubes with a rectangular cross section have been fabricated through a facile solution approach. The as‐prepared GeSe microtubes have diameters in the range of 1–2 μm and wall thicknesses of approximately 100–200 nm. Crystal growth along the [010] direction is preferable for the GeSe microtubes. The formation of GeSe microtubes is proposed to originate from an etching effect of the solvent oleylamine. A clear photoresponsive behavior has been found for the as‐synthesized GeSe microtubes. The products were characterized by using powder XRD, energy‐dispersive X‐ray spectroscopy, TEM, SEM, and UV/Vis spectrophotometry.
Single‐crystalline GeS nanosheets and nanowires have been selectively synthesized by simply varying the reaction conditions via a convenient wet chemical approach. The formation mechanism of the nanosheets and nanowires has been proposed. The results from time‐dependent reactions proved that the GeS nanowires were formed by a rolling‐up mechanism. Films made of as‐synthesized GeS nanosheets and nanowires were found to have an outstanding photoelectric response, suggesting their potential in solar energy applications. The structure, morphology, composition and optical absorption properties of the as‐prepared samples were characterized using X‐ray powder diffraction, transmission electron microscopy, energy‐dispersive X‐ray spectrometry and scanning electron microscopy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
