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 ...
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...

The effect of fluorine substitution on the spectral properties of the xZnF2–(20-x)ZnO–40As2O3–40TeO2 (x=0, 4, 8, 12, 16 and 20mol%) glass system was investigated by FTIR and Raman spectroscopies. The results demonstrate that TeO4 and TeO3 were among the primary structural units ...
Strong exciton-LO phonon and exciton-Frhlich mode coupling in ZnO nanostructures is deduced from the analysis of multiphonon excitonic resonant Raman scattering. 展开 关键词: II-VI semiconductors Raman spectra energy gap nanostructured materials phonon-exciton interactions photoluminescence polaritons ...
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 ...
Enhanced photoluminescence, Raman spectra and field-emission behavior of indium-doped ZnO nanostructures Indium-doped (In-doped) ZnO nanostructures with four different morphologies, namely nanochips, nanotripods, nanorods, and nanodisks, have been successfully...

Visible photoluminescence (PL) broad bands are observed in the Raman spectra of SiC nanoparticles (np-SiC) with diameters ranging from 10 to 25 nm. The phenomenon is studied versus the particle size, chemical composition, annealing, and oxidation treatments. In the case of quasistoichiometric np-...
The Raman spectra of unimplanted and Cu+ ion implanted samples of nanostructured ZnS showed LO mode and LOPC (L−) mode. The peak position of LOPC mode decreased with increase in implantation dose due to the passivation of free electrons by Cu+ ions. 展开 关键词: Nanoparticles Ion ...
