Raman spectra of moo3 implanted with protons
Webb14 maj 2024 · This work reports on the in situ strategy to reversibly generate or suppress oxygen vacancies on α-MoO3 which were probed by Raman spectroscopy. Reversible changes in two features of the α-MoO3 Raman spectrum could be correlated to the generation of oxygen vacancies: displacement of the Tb band frequency and the in … Webb20 apr. 2024 · Chemically _ driven isothermal close space vapour transport was used to prepare pure MoO2 films which were eventually converted to MoO3 by annealing in air. According to temperature_dependent Raman measurements, the MoO2/MoO3 phase transformation was found to occur in the 225 _ 350 oC range; no other phases were …
