RAMAN SCATTERING IN NANOSCALE TIN DIOXIDE
Photoelectronics, 2015 The Raman scattering spectra peculiarities are analyzed for nanosized samples of tin dioxide using the authors’ own research and the available literature. The presented results show the series of differences in RS spectra in the nanoobjects in comparison with the bulk material. The principle peculiarities comprise: the broadening of peaks, the spectra ‘
