摘要
Er-doped Y_(2)O_(3),Bi_(2)O_(3)and Sb_(2)O_(3)nanoparticles are synthesized using pulsed laser ablation in a liquid.Ceramic targets of Y_(2)O_(3):Er^(3+),Bi_(2)O_(3):Er^(3+)and Sb_(2)O_(3):Er^(3+)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.
