摘要

报道了一种制备浸没在多孔玻璃微球中的Eu3+的方法。利用扫描电镜(SEM)和透射电镜(TEM)对制备的玻璃微球和多孔玻璃微球进行了表征，并分别估算了玻璃微球的尺寸和多孔玻璃微球的孔径大小。测试了铕在多孔玻璃微球中的光致发光光谱。荧光光谱和发射光谱表明，浸没在多孔玻璃微球中的Eu3+的特性是由于D0 F0、D0 F1和D0 F2随波长增加而发生的跃迁。浸没在多孔玻璃微球中的eu3 +，荧光光谱和发射光谱，SEM, TEM

Fabrication of Eu3+-Immersed in Porous Glass Microspheres and Fluorescent Characterizations

A method to fabricated Eu3+-immersed in porous glass microspheres is reported. The fabricated glass microspheres and the porous glass microspheres are characterized by scanning electroscopy (SEM) and transmission electron microscopy (TEM), and the sizes of glass microspheres and the sizes of aperture of the porous glass microspheres are estimated, respectively. The photoluminescence spectroscopy of the Euimmersed in porous glass microspheres is tested. The fluorescent and emission spectra indicate that the characteristics of the Eu3+immersed in porous glass microspheres result from D0 F0, D0 F1 and D0 F2 transitions with increasing wavelength. Keywords-Eu3+-immersed in porous glass microspheres, fluorescent and emission spectra, SEM, TEM
