The peculiarities of reduction and doping of vanadium oxides probed by TDPAC spectroscopy at ISOLDE (original) (raw)

We propose a continuation of the study of intrinsic effects in vanadium oxides. The mechanism of temperature induced reduction in V 2 O 5 is to be probed by TDPAC spectroscopy with 111m Cd probes implanted at ISOLDE. We expect to extract information on the dynamics of oxygen vacancies and identify all the reduction products. In addition, a study of cadmium meta-and pyrovanadates is to be performed in order to elucidate the nature of Cd doping in V 2 O 5 . We intend to test the hypothesis that, even at low concentrations of the divalent metal, vanadate formation is favored and not substitutional doping. Requested shifts: 6 shifts (split among two probe isotopes according to ISOLDE schedule)
