摘要：

Eu3+ doped Y(OH)(3)@beta-NaYF4 core-shell nanotubes were prepared by an in situ synthesis method. The photoluminescence properties were studied under different excitation wavelengths. When the excitation wavelength is 363, 380, and 397 nm, the spectral configurations are similar, and are different from that under 414 nm excitation. The peak location of F-7(0) -> D-5(3) shifted with excitation wavelength, indicating that the nanocrystals have multiple luminescence centers or emitting states.
