2020年6月10日 · SnO particles were synthesized by an alkali-assisted hydrothermal and microwave methods. The aqueous-based reactions were carried out at pH ~ 8, under inert atmosphere (Ar). The reactions were...

SnO prepared by soft chemistry exhibits a black color and semiconducting properties. The X-ray diffraction indicates a tetragonal symmetry (SG: P4/nmm) with nano crystallites of average size of...

The XRD spectrum from the SnO powder heating at 450° C (Fig. 1c) shows a very strong feature of texture structure.

2022年9月12日 · For SnO x samples deposited at 100 °C and annealed at 400 °C under moderate vacuum, similarly to as-deposited samples at 100 °C without O 2 flow, XRD pattern shows a broad peak at around 30 ...

X-ray diffraction (XRD) analysis indicates that the as-synthesized SnO 2 nanocrystallites consists merely of a rutile-type SnO 2 with tetragonal crystallographic structure. Scanning electron microscope (SEM) observation shows that the prepared SnO 2 nanoparticles are regularly rhombus in shape.

2020年4月27日 · The obtained XRD pattern corresponds to the tetragonal (rutile) phase of the SnO 2 crystal structure as confirmed by the JCPDS data 41-1445 and 88-0287 [14, 19]. Table 1 summarizes the major peak position (2θ), the d-spacing that represents interplanar distance, miller indices, and FWHM of the three samples.

2012年7月27日 · SnO 2 nanoparticles have been successfully synthesized by a simple hydrothermal method at low temperature using hydrazine hydrate as a mediator. The structural, morphological, microstructural, and optical properties of a SnO 2 sample were investigated. XRD spectra indicated that the as-prepared product is polycrystalline in nature.

2013年12月5日 · A range of diagnostic techniques including X-ray diffraction (XRD), UV–visible absorption, atomic force microscopy (AFM), scanning electron microscopy (SEM), and synchrotron-based X-ray photoelectron spectroscopy (XPS) were used to investigate structural, optical, and electronic properties of the resulting film.

The observed XRD pattern confirms the formation of pure SnO2 polycrystalline phase, corresponding to a tetragonal crystal system with P42/mnm space group, and is found to be ...

Our study involves the preparation of two different samples of SnO2 nanoparticles by chemical co-precipitation method by using two different precursors SnCl2.2H2O and SnCl4.5H2O. We were able to identify a better sample for fabrication of SnO2 gas sensor which lies in our future plan of work. 2. Experimental.
