采用溶胶-凝胶法和超临界干燥技术制备了（1－n）SiO2－nAl2O3（n=0、001、0.1）混合气凝胶体系，并以此作为载体，成功地将纳米ZrO2粒子组装到（1—n）SiO2－nAl2O3介孔体系中，而形成纳米ZrO2／（1—n）SiO2－nAl2O3介孔复合材料．光致发光光谱研究表明，室温下以316um（392eV）波长激发时，纳米ZrO2粒子540um（230eV）荧光峰，在介孔复合体中将蓝移至400um（310eV）左右，蓝移量140um；其光致荧光峰的相对强度亦随Al2O3的掺入量不同而不同．对产生上述光谱性质变化的机理进行了初步探讨．
(1-n) SiO2-nAl2O3 (n = 0,001,0.1) airgel system was prepared by the sol-gel method and the supercritical drying technique. Using this as a carrier, the nano-ZrO2 particles were successfully assembled into (1-n) SiO2-nAl2O3 mesoporous system to form nano ZrO2 / (1-n) SiO2-nAl2O3 mesoporous composite materials. The results of photoluminescence showed that when excited at 316 um (392 eV) at room temperature, the fluorescence peak of 540 nm (230 eV) of nanosized ZrO2 particles shifted blue to about 400 um (310 eV) in the mesoporous complex with a blue shift of 140 μm. The relative intensity of the photoluminescence peak also varies with the amount of Al2O3 incorporated. The mechanism of the above-mentioned changes of spectral properties has been discussed preliminarily.
