The XPS Cu 2p and Mn 2p spectra are not informative, since the low quantities of doping elements (5% or 2.5%) are associated with peaks characterized by very low intensities and hard to be observed or deconvoluted. Raman analyses Analyses at room temperature Raman spectroscopy can provide useful...

Survey spectra of samples were collected over the 1100 eV range at a resolution of 1 eV per step, 100 ms and 150 eV of pass energy. High-resolution spectra were collected for the chemical species of interest at a resolution of 0.1 eV per step and 20 eV of pass energy. All measurements...
