Witryna19 gru 2024 · The NCA 177 Lu and pure 175 Yb were produced with radionuclidic purity of 99.99 and 99.97% respectively by irradiation of enriched 176 Yb target in thermal neutron flux of 5 × 10 13 n/cm 2 s for 14 days. 177 Lu-DOTMP and 175 Yb-DOTMP were obtained with high radiochemical purities (> 95%) under optimized reaction conditions. Witryna3 and 1 mol.% Yb 2 O 3 makes it possible to obtain transparent homogeneous crystals with a pseudocubic structure, which have high phase stability. • The conductivity of the crystals depending on the concentration of Yb 2 O 3 is nonmonotonic. • The (ZrO 2) 0.9 (Sc 2 O 3) 0.09 (Yb 2 O 3) 0.01 crystals have a maximum conductivity in the ...
