From Raman result show peaks at 81 cm−1 and 303 cm−1, are the specific bands of α-Bi2O3. The band at 303 cm−1, are assumed to be because of Bi–O stretches. The electrical properties such as barrier height (ΦB) and ideality factor (n) of the Al/Bi2O3NPs/PS/Si/...
The broad absorption peak observed around 3296 cm⁻¹ is attributed to the O–H stretching vibrations, indicating the presence of alcohol, carboxylic acid, or phenol functional groups. The medium absorption peak at 2924 cm⁻¹ corresponds to the C-H stretching vibrations. The absorption peak...
From Raman result show peaks at 81 cm(-1) and 303 cm(-1), are the specific bands of alpha-Bi2O3. The band at 303 cm(-1), are assumed to be because of Bi-O stretches. The electrical properties such as barrier height (Phi(B)) and ideality factor (n) of the Al/Bi(2)O(3)...
3 Raman spectra of glass flux with different n( Bi2 O3 ) / n( SiO2 ) 图3 为玻璃熔剂的拉曼光谱,从图 3 中可以看出,伴随着 n( Bi2 O3 ) / n( SiO2 ) 逐渐升高,光谱中 135 cm - 1 处[ BiO3 ] 基团中 Bi3 + 的振动峰强度[19-20] 、394 cm - 1 处 [ BiO6 ] 基团中 Bi—O—...
The Raman spectrum shows three strong peaks, at 255, 382, and 491cm-1. The emission peak from the Er3+: 4I13/2 4I15/2 transition locates around 1.53-碌m with a full width at half maximum (FWHM) of ~78 nm. The theory lifetime of the 4I13/2 level is ~2.85ms. The emis...
The structure of PbO BiO 1.5 GaO 1.5 glasses has been investigated by IR and Raman spectroscopy. An infrared absorption band involving four-coordinated Ga 3+ ions was observed at about 610–650 cm 1 . The peak of this band shifts toward higher wavenumbers with increasing GaO 1.5 content, ind...
Fig. 5. (a) FTIR spectra were obtained for bare g-C3N4, Bi2O3:1 mol% Eu3+ (ppt) and Bi2O3:1 mol% Eu3+/7 wt% g-C3N4 and (b) Raman spectra (λExc: 633 nm) of bare g-C3N4, Bi2O3:1 mol% Eu and Bi2O3:1 mol% Eu3+/x wt% g-C3N4 (x = 1–7 wt%) composites...
The well-defined peaks in the infrared spectra located at 470 cm−1are due to the vibration in the local symmetry of highly distorted BiO6polyhedral units and/or BiO3units and/or bending of BO4units31,32. Another IR peak at 542 cm−1may be attributed to Bi–O and Bi–O–Bi stret...
The Raman spectra have revealed the Boson peak at low frequencies (≈62–72 cm−1), various functional groups of primary glass forming units like [BO4], [BiO3], [CrO4]2− and [ZrO4] units, and other glass modifying units/crystallite units viz., [BO3], [BiO6], [CrO6], BOB ...
Therefore, the X-ray diffraction pattern of such material shows sharp peaks while the Raman bands are broad and similar to those of the parent glass. The anti-glass was first studied by Trömel et al. in 1983 [21]. Only few anti-glass structures have been reported in the literature ...
