2021年2月5日 · In this paper, we analyzed the Raman spectra of bismuth oxide physical vapor as-deposited thin films aiming to use the spectroscopy as a method to identify the film structure.

2021年8月1日 · Raman Spectroscopy reveals crystal structure in thin layers of Bi onto SiO2 substrate. Bismuth films are not oxidized immediately after the ambient exposition. Bismuth films characterized via AFM, SEM, XRD and Raman spectroscopy.

2018年8月3日 · Herein, we combined theoretical and experimental approaches to study the Raman spectra of Bi 2 O 2 Se and related bismuth oxychalcogenides (Bi 2 O 2 Te and Bi 2 O 2 S). The experimental peaks lie at 160 cm –1 in Bi 2 O …

1992年4月1日 · The empirical bond length/bond strength/Raman stretching frequency relationships lead to a unique and effective method of interpreting Raman spectra of bismuth oxide species. This method allows the systematic determination of the Bi O bond lengths and oxygen coordination of a BiO x polyhedron from its Raman spectrum.

A new method is presented for interpreting the Raman spectra of bismuth oxides. The method relies on empirical relations between bismuth-oxygen (Bi-0) bond lengths, bond strengths, and Raman stretching frequencies. A least-squares exponential fit of crystallographically determined Bi …

2024年3月18日 · Bismuth, the heaviest of all stable group V elements with strong spin-orbit coupling, is famously known to exhibit many interesting transport properties, and effects such as Shubnikov-de Haas and de Haas-van Alphen were first revealed in its bulk form.

2011年5月23日 · We report on Raman spectroscopy of few quintuple layer topological insulator bismuth selenide (Bi 2 Se 3) nanoplatelets (NPs), synthesized by a polyol method. The as-grown NPs exhibit excellent crystalline quality, hexagonal or truncated trigonal morphology, and uniformly flat surfaces down to a few quintuple layers.

2023年6月1日 · Here, we synthesize using an unprecedented colloidal photocatalyzed, one-pot redox reaction a few-layers bismuth hybrid of “electronic grade” structural quality.

Raman spectroscopy image shows the different vibrational modes of bismuth oxide nanoparticle within the range of 50–500 cm⁻¹. The band at 1400 cm⁻¹ in the Raman spectrum indicates the...

2009年2月13日 · Inspired by the discovery of bismuth metal used as a pigment in a fifteenth century illuminated manuscript, the identification of bismuth compounds by Raman spectroscopy is investigated. Raman spectra of bismuth metal powder, bismuth (III) sulfide (Bi 2 S 3) and bismuth (III) oxide (α-Bi 2 O 3) are presented.
