This study investigates how rare earth ion (RE3+) concentration affects stabilization of the crystalline structure and infrared-to-visible upconversion (UC) in Er3+/Yb3+ co-doped yttrium tantalates, synthesized by the sol–gel method. Under 980 nm,

Luminescent spherical, redispersable, and monodisperse Er3+,Yb3+ co-doped Y2O3 nanoparticles were synthesized by homogenous precipitation followed by thermal annealing. Cubic Y2O3 nanoparticles exhibited high colloidal stability in water and biologic
