Resumo
Advances toward new materials for dosimetry application is essential to enhance quality assurance and quality
improvement practices based on radiation protection concept. Face to this challenge the present work reports an
approach to produce thulium-yttria nanoparticles with electron paramagntic resonance response by an alternative
hydrothermal synthesis based on a relative low temperature and pressure. Distinct compositions of
thulium-yttria nanoparticles with up to 2 at.%Tm (at.%, atomic percentage) were prepared and characterized by
XRD, SEM, PCS, and EPR. The proposed synthesis method followed by thermal treatment of the precursor powder
at 1100 ◦C for 2 h provided thulium-yttria nanoparticles with rounded shape, cubic C-type structure, and mean
particle size (d50) less than 160 nm. Among all compositions formed, thulium-yttria nanoparticles prepared with
0.1%Tm presented the most remarkable EPR response. The production of fine thulium-yttria nanoparticles with
EPR response supply meaningful parameters to advance in the formation of new dosimetry materials based on
rare earths.
