摘要

Er-doped Y2O3,Bi2O3 and Sb2O3 nanoparticles are synthesized using pulsed laser ablation in a liquid.Ceramic targets of Y2O3∶Er3+,Bi2O3∶Er3+ and Sb2O3∶Er3+ for ablation process are prepared by standard solid-state reaction technique and ablation is carried out in 5-ml distilled water using nanosecond Q-switched Nd∶YAG laser.The morphology and size of the fabricated nanoparticles are evaluated by transmission electron microscopy and the luminescence emission properties of the prepared samples are investigated under different excitation wavelengths.
