| 英文摘要 | The effects of irradiation on CaWO4, SrWO4, BaWO4, YVO4, LaVO4, YNbO4, and LaNbO(4)were investigated on thin crystals using 1.0 MeV Kr ions at 50-1000 K. All of the ABO(4)compounds can be amorphized with calculated damage cross sections (sigma(a) = 1/F-c0) in the range of similar to 0.30-1.09 x 10(-14)cm(2)ion(-1)at zero Kelvin. The analysis of fluence-temperature data returned critical temperatures for amorphization (T-c) of 311 +/- 1, 358 +/- 90, 325 +/- 19, 415 +/- 17, 541 +/- 6, 636 +/- 26, and 1012 +/- 1 K, respectively, for the compounds listed above. Compared with previous in situ irradiation of ABO(4)orthophosphate samples using 0.8 MeV Kr ions, theT(c)values of LaVO(4)and YVO(4)are higher than those of LaPO(4)and YPO(4)by 82 K and 124 K, respectively. TheT(c)values of the three scheelite structures, CaWO4, SrWO4, and BaWO4, indicate that they are the most radiation tolerant compounds under these conditions. The A-B cation anti-site energies,E-fAB, determined by DFT range from 2.48 to 10.58 eV and are highly correlated with the A-B cation ionic radius ratio,r(A)/r(B), but are not correlated withT(c)across the different structure types, suggesting that the formation and migration energies of Frenkel defects play a more important role in damage recovery in these compounds. We also discuss the role of cation and anion charge/iconicity as determined by DFT. ABO(4)compounds with the zircon structure and B = P or V have a distinct advantage over those with B = Si as the damaged regions do not appear to be significantly affected by polymerization of (PO4)(3-)or (VO4)(3-)groups which might stabilize the amorphous fraction and ultimately lead to phase separation as observed in zircon (ZrSiO4). |
