摘要：
Ce3+:Y2O3, Pr3+:Y2O3, Ce3+:(LaxY1-x)(2)O-3, Pr3+:(LaxY1-x)(2)O-3 nanoparticles were fabricated by laser ablation. The nanopowders consisted of spherical particles with average size of 14 divided by 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 10(6) W/cm(2) with close-to-Gaussian profile. The structural and morphological properties of the nanoparticles were investigated employing TEM, BET, FT-IR, XRD analysis. (C) 2020 Elsevier B.V. All rights reserved.
