Zusammenfassung:•(Ce3+,Pr3+):Y2O3,(Ce3+,Pr3+):(LaxY1−x)2O3 nanopowders were obtained by laser ablation.•Nanoparticles consist of spherical particles with an average size of 14 ÷ 17 nm.•Structural and morphological properties of nanoparticles were investigated in detail. Ce3+:Y2O3, Pr3+:Y2O3, Ce3+:(LaxY1−x)2O3, Pr3+:(LaxY1−x)2O3 nanoparticles were fabricated by laser ablation. The nanopowders consisted of spherical particles with average size of 14 ÷ 17 nm. Ytterbium fiber laser operated in pulse mode at 5 kHz repetition rate and average radiation power of 255 W. The intensity of the laser radiation in focal spot was about 106W/cm2with close-to-Gaussian profile. The structural and morphological properties of the nanoparticles were investigated employing TEM, BET, FT-IR, XRD analysis.
