| Аннотация |
The EPR spectroscopy and magnetization measurements were used to study the effect of an
nealing conditions on the local structure of Er3+ ions in CeO2 : 1% Er3+ nanoparticles. The
nanoparticles were synthesized using the coprecipitation technique from an aqueous solution of
cerium nitrate and hexamethylenetetramine.
A correlation was found between the EPR spectra of the Er3+ ions, magnetization and lumines
cence, depending on the annealing atmosphere, which proved the crucial role of oxygen vacancies
in the origin of magnetism in CeO2 nanoparticles.
EPR lines due to trigonal centers were clearly detected in CeO2 : 1% Er3+ nanoparticles annealed
in a vacuum, while no such lines were found for similar nanoparticles annealed under argon or air atmospheres |
