As such, these spectra clearly do not correspond to any known spectrum of a pure standard zirconia phase. Therefore, the analysis conducted in this paper aims to provide a better understanding of these peculiar Raman features. For that purpose, specific ion‐irradiated samples were analysed. In ...

Raman spectra of TiO2 films prepared via the sol–gel process were studied by UV and visible Raman spectroscopy. The evolution of the phases of TiO2 films during annealing was investigated, and the relative intensities of the Raman bands excited with 325 nm were found to be distinct from those...
Based on the Raman spectra excited at three different wavelengthsi.e.488, 514 and 633 nm and measured in the spectral range of 150–4000 cm1the correlation between the phonon spectra of ZrO2and luminescence of europium is clearly evidenced. The PL investigations span a variety of steady-state ...
