“…For the sample irradiated with 1×10 13 U-ions/cm 2 , e.g., the tetragonal fraction is limited to (90.1 ± 4.4) %. In agreement with previous measurements [9,5], the transformation from monoclinic to tetragonal is obviously never complete. It is important to point out that the tetragonal structure of ZrO 2 obtained by simple temperature increase is not stable at room temperature.…”

“…After releasing the pressure, the sample was carefully analyzed by Raman spectroscopy applied to different sample locations. As described earlier in [9], some regions exhibit no change at all, whereas other regions are completely transformed into the tetragonal phase. In total, the fraction of completely transformed regions is ∼ 10 % (see Fig.…”

“…5) at around 4 GPa. In our previous work [9], we ruled out that the lower transition temperature of the ortho-I-to-tetragonal transition compared to the monoclinic-totetragonal transition is the decisive parameter. At pressures of 4.3 and 7.6 GPa, no enhanced radiation response appeared.…”

“…Additional pressure was shown to enhance or hinder certain radiation induced transformations [7,8]. Conversely, ion irradiation can change the stability field of some materials [6,9]. The exposure of pressurized samples to ion beams also provides insight how pressure-induced phase transitions in minerals may be affected by pre-existing damage and by the microstructure of the starting material.…”

In this study, we demonstrate that the combination of relativistic heavy ions with pressure can influence the phase behavior of ZrO 2 in ways none of those two extreme conditions alone could. The response behavior of ZrO 2 towards ion irradiation under different pressure conditions is investigated. ZrO 2 exposed to energetic particles is known to undergo a crystalline-to-crystalline phase transition from the monoclinic to the tetragonal phase. In agreement with earlier findings, this structural change requires also for heaviest ions, such as Au, Pb, and U, a multiple ion impact. If the irradiation is performed under high pressure, the monoclinic-to-tetragonal transformation occurs at a fluence that is more than one order of magnitude lower suggesting a single impact process. Raman measurements at ambient conditions and X-ray diffraction analysis of the samples irradiated under pressure revealed that the monoclinic-to-tetragonal transformation under pressure is not a direct process but involves a transition into the cubic high-temperature structure, before the tetragonal structure becomes stable under decompression. At even higher pressures, the additional ion irradiation forces ZrO 2 to transform to the higher orthorhombic-II phase that is far away from its stability field. straße

“…Recent reports show that these techniques have been widely used for studying the irradiation induced effects on various class and different properties of materials [6][7][8]. Available reports indicate that various vibrational modes exhibit different sensitivity towards irradiation [9][10][11][12][13] but no discussion has been made on possible cause for such modifications [14].…”

Present work aims to investigate the effect of Y 3+ -substitution and 50 MeV, Li 3+ ion irradiation (fluence: 5 x 10 13 ions/cm 2 ) on infrared spectral evolution of Y 3+x Fe 5-x O 12 (x = 0.0, 0.2 0.4, 0.6, 0.8 and 1.0) garnet system. Infrared absorption spectra for x = 0.0 -0.6 compositions show three absorption bands while x = 0.8 -1.0 compositions are characterized by two absorption bands, identical with IR spectra of rare earth ortho ferrites. The position and intensity of bands are found to be influenced by Y 3+ -substitution. The intensity of absorption bands for x = 0.0 -0.4 compositions is found to increase, while for x = 0.6 -1.0 compositions no effect of swift heavy ion irradiation has been observed. The results have been explain in the light of SHII induced defect states, partial removal of un-wanted YFeO 3 phase and change in structural parameters. It seems that YFeO 3 phase is irradiation hard phase.

Recently, unusual Raman signals were observed in different works conducted on thin zirconia layers grown on zirconium alloys simulating in-reactor materials after high fluence ion irradiation or for samples cut from fuel rods irradiated in nuclear plants. 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 situ Raman spectroscopy was first used to follow the irradiation process. Then, samples were characterized using different excitation wavelengths. Finally, the effects of oxygen isotopic substitution were examined in details. Results are discussed in terms of disorder and size-related effects.
