The new results are presented of the experimental study of KNbO3 and KTaO3 by means of X-ray photoelectron spectroscopy, soft X-ray emission and X-ray fluorescence spectroscopy. In particular, Nb M4,5 spectra (5p 4f → 3d5/2, 3/2 transition) have been measured over a range of near-threshold excitation energies 206.5 – 240.6 eV, and Ta N3 spectra (5d 6s→ 4p3/2 transition) over 399.4 – 420.4 eV at...

In this study, Eu-doped CdSe nanoparticles with variable Eu3+ content were synthesized by a simple sonochemical method. Eu3+ substitution into the structure of CdSe resulted in a material with new physical properties, composition and morphology. The synthesized nanoparticles were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscop...
