Resumo
In the radiation dosimetry field the research for new materials is a continuos demand with the aim to provide
highly improvement procedures where ionizing radiation is used. Considering this challenge, the present work
reports the colloidal synthesis of europium-thulium-co-doped yttria powders (YET) and evaluates the dopants
effect on the promotion of EPR response of yttria. The powdered compositions prepared with up to 2at.%Tm and
2at.%Eu (at.%, atomic percentage) were evaluate by XRD, PCS, SEM, and EPR. Based on the results, the proposed
synthesis method provided ceramic powders with cubic C-type form and mean particle size (d50) less than
160nm. The most significant EPR dose-response was noticed for the powdered composition prepared with 0.5at.
%Tm (YET0.5) as irradiated with 5kGy (60Co). These findings are key parameters to advance toward the formation
of new materials for radiation dosimetry.
