Silica coated bismuth sulfide (Bi2S3) nanorods have been prepared by a simple coating process. The coating resulted in the improved stability and luminescent intensity of the Bi2S3 nanorods. Hollow silica nanotubes were also obtained by using Bi2S3 nanorods as a removal template. r 2005 Elsevier B.V. All rights reserved. PACS: 81.05.Ys; 81.20. n

The increased use of diagnostic x-rays, especially in the field of medical radiology, has necessitated a significant demand for high resolution, real-time radiation detectors. In this regard, the photoresponse of bismuth sulfide (Bi2S3), an n-type semiconducting metal chalcogenide, to low energy x-rays has been investigated in this study. In recent years, several types of nanomaterials of Bi2S3...

Semiconducting bismuth sulfide (Bi2S3) nanoplates with unique highly oriented {001} surfaces were prepared on a large scale using a novel organic precursor Bi(DTCA)3 (DTCA = carbazole-9-carbodithioic acid). The as-prepared Bi2S3 nanoplates were dispersed in dimethyl sulfoxide (DMSO) and spin-coated onto an indium tin oxide (ITO) coated glass substrate. With a simple ITO/Bi2S3/Al stacked structu...

Core/shell heterostructure composite has great potential applications in photocatalytic field because the introduction of core can remarkably improve charge transport and enhance the electron-hole separation. Herein, hierarchical Bi2S3/In2S3 core/shell structured microspheres were prepared via a simple one-pot hydrothermal process based on different growth rate of the two kinds of sulphides. Th...

Non-invasive and real-time imaging of the gastrointestinal (GI) tract is particularly desirable for research and clinical studies of patients with symptoms arising from gastrointestinal diseases. Here, we designed and fabricated silica-coated bismuth sulfide nanorods (Bi2S3@SiO2 NRs) for a non-invasive spatial-temporally imaging of the GI tract. The Bi2S3 NRs were synthesized by a facile solvot...

A comprehensive method to evaluate the thermoelectric performance of one-dimensional nanostructures, called the T-type method, has been first developed. The thermoelectric properties, including the Seebeck coefficient, thermal conductivity and electrical conductivity, of an individual free-standing single crystal Bi2S3 nanowire have been first characterized by applying the T-type method. The de...

Thin films of Bi2S3 of different thickness have been prepared on glass substrates in various temperatures by Chemical bath deposition. The thickness of the deposited film is measured by employing quartz crystal monitor method. The micro structural parameters such as grain size, dislocation density and strain have been evaluated. The lattice parameter values ‘a’ and ‘c’ have been determined and ...

In this work, we fabricated a novel photoelectrochemical immunosensor for assay of DNA methylation, where Bi2S3 nanorods were used as photoelectric conversion material, MBD1 protein (a kind of methyl bonding domain protein) was used as DNA methylation recognizing unit, anti-his tag antibody was used to further inhibit the photocurrent and increase the detection sensitivity. The results demonstr...

To study the degradation of tetracycline by Bi2S3-based binary composite and ternary photocatalysts, Cu2O/Bi2S3 NH2-UiO-66/BiOBr/Bi2S3 was successfully fabricated solvothermal method, which can effectively stably degrade (TC). The crystal structure, chemical composition, microscopic morphology as-prepared sample were analysed X-ray diffraction (XRD) scanning electron microscopy (SEM). photocata...

Lattice-strained Bi2S3 with 3D hierarchical structures are prepared through a top-down route by topotactic transformation. High-resolution transmission electron microscopy and X-ray diffraction (XRD) confirm the lattice spacing is expanded prolonged sulfuration. Performance studies demonstrate that largest expansion (Bi2S3-9.7%, where 9.7% represents expansion) exhibits greater electrocatalytic...
