摘要/Abstract

摘要： 采用锐钛矿型二氧化钛为原料, 通过浮区法制备金红石型二氧化钛单晶. 通过X射线衍射（XRD）和拉曼散射（Raman）测试, 对单晶体的结构进行表征, 表明晶体为典型的金红石相. 在Raman光谱中可观测B_1g(143 cm^-1),E_g(446 cm^-1),A_1g(605 cm^-1)和B_2g(826 cm^-1)4个Raman活性模, 并观测到可能属于2级Raman散射峰, 如273,316,327,519,700 cm^-1.

Abstract: A rutile (TiO₂) single crystal was prepared via floating zone grower with natural anatate (TiO₂) powder as starting material. It was characterized by X-ray diffraction (XRD) and Raman scattering. The four characteristic Raman peaks (143,446,605,826 cm^-1) verify that the as-grown crystal has a typical rutile phase. Some other peaks such as 235,273,316,327,519,700 cm^-1 were simultaneously observed. 

Key words: floating zone, rutile, X-ray diffraction, Raman scattering
