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B1g(143 cm-1),Eg(446 cm-1),A1g(605 cm-1)和B2g(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.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.
