掺Eu^(3+)的Al_2O_3纳米粉末的制备及表征

Preparation and Characterization of Eu^(3+) - doped A1_2O_3 Nanocomposites

采用溶胶-凝胶法制备了Al2O3-EuAlO3纳米复合粉末,并用XRD谱图和Raman光谱进行表征.分析了第二相EuAlO3的引入对α-Al2O3的晶化温度的影响,以及Al-O键与Eu-O键振动频率的变化.

We investigated the Al2O3 - EuAlO3 nanocomposites prepared by sol - gel method through XRD and Raman spectra. The effect of the adition of EuAlO3 on crystallization of Al2O3 and the change of vibrational frequencies of Al - O and Eu - O stretching bands were also discussed.
