Abstract
Sm2+-doped Al2O3-SiO2 glasses with three-dimensionally interconnected macroporous morphology have been prepared via the alkoxy-derived sol-gel process containing poly (ethylene oxide) and SmCl3·6H2O. The macroporous morphology is obtained by concurrently inducing the phase separation and sol-gel transition. Using a visible laser with the wavelength of 488 nm, the valence state of Sm2+ has been manipulated spatially. When the photoionization of Sm2+ is combined with multiple light scattering in the porous glasses, holes are burned in wave-vector domain. The hole profile can be controlled by adjusting the macroporous morphology.
