Raman spectra of ZnO powders prepared by firing ZnOprecipitate were reported in detail for the first time. By comparing the spectra with that of the sample fabricated by another method and analyzing frequency difference between the focused-laser irradiated samples with different firing temperature in ...

We measured the Raman spectra of ZnO nanoparticles (ZnO-NPs), as well as transition-metal-doped (5% Mn(II), Fe(II) or Co(II)) ZnO nanoparticles, with an av... SatoBerrú, R. Y,VázquezOlmos, A,FernándezOsorio, A. L,... - 《Journal of Raman Spectroscopy》 被引量: 119发表: 20...
In Raman spectra of ZnBr2-KBr-PbBr2 glasses, the dominant bands are observed at about 60cm-1 and 155cm-1 or 174cm-1. The 60cm-1 band was assigned to the mode containing bending vibrations and the 155cm-1 or 174cm-1 band to the symmetric mode containing the stretching vibration between...
IR and Raman SpectraBi 2 O 3 -ZnO-B 2 O 3 -BaO Quaternary Glass SystemStructureAmong new low-melting-point glasses, bismuth ate glass is deemed to have the most potential as an environmentally friendly replacement for polluting Pb-containing glasses. Current studies of boro-bismuthate glasses...
It encourages finding a unique reason behind the observation of forbidden modes in the Raman spectrum of ZnO nanowires. Further, there is a lot of controversies occurred on the observation of anomalous Raman modes, especially B1low and B1high in the Raman spectra of ZnO. Tzolov et al. found...
Further, the Raman spectra of 0D ZnO-immobilized PVDF nanocomposite has been well investigated by Indolia and Gaur in a recent report [82]. Improvement of the crystalline feature of PVDF was witnessed to be increased by the incorporation of ZnO nanoparticles. This refers to the strong ...
It was found that Raman peaks (bands) at 130 and 578 cm-1 appeared in the spectra of ion-implanted ZnO samples, which are independent of the ion species, whereas a new peak at 274 cm-1 was found only in N-ion implanted samples, and Raman band at 470 cm-1 was found clearly in ...
