摘要：

One-dimensional La2O2S:Eu3+ nanowires (NWs) were fabricated with a simple hydrothermal method. The structures were characterized by X-ray diffraction and transmission electron microscopy (TEM). The photoluminescent properties including excitation and emission spectra were studied. The results indicated that in excitation spectra there existed charge transfer (CT) absorption of both O2--> Eu3+ and S2--> Eu3+, and f-f transitions absorption in NWs and corresponding sub-meter materials (SMs). The relative intensity of CT absorption of O2--> Eu3+ to S2--> Eu3+ in both samples clearly changed. The strong yellow and red emissions of Eu3+ ions in NWs were observed.
