Ytterbium‐doped yttrium oxide (Yb:Y 2 O 3 ) transparent ceramics with different sintering additives (Lu 2 O 3 , Sc 2 O 3 , CeO 2 , ZrO 2 , or HfO 2 ) were fabricated using nanopowders produced by laser ablation. Transmission and photoluminescence spectra of the obtained ceramics were investigated at room temperature. Highest in‐line transmittance was over 80% at the wavelength of 1060 nm for 2 mm thick Yb:Y 2 O 3 ceramics with zirconium and hafnium. Divalent Yb ions with the ground state electron configuration 4f 13 6s were revealed. The absorption and emission bands caused by s↔s transitions of these ions were observed in the IR spectral range of Yb 3+ ions. The superposition of both Yb 3+ and Yb 2+ emission bands leads to an effective broadening of the whole luminescence band.
