Abstract: | Nanocrystalline (<5 nm) quasi-ternary ceria-based solid solutions doped with REE (Er, Eu, Y) in various concentrations (5–20
mol %) were prepared by homogeneous hydrolysis in the presence of hexamethylenetetramine (HMTA). Physicochemical characteristics

R0.2 − y
O2 - δ (R = Er, Yb) solid solutions were analyzed. |
