Luminescencent Properties of Sm3+ Doped TiO2 Powders Prepared by Sol-Gel Method

  • 摘要: 采用溶胶凝胶法制备了Sm3+掺杂的TiO2粉体,并表征了其性能.结果表明溶胶凝胶法制得粉体为锐钛矿和金红石的混相TiO2.在335 nm波长光的激发下,有较强的橙红色发射,发射峰值分别位于582、611、662和725 nm,属于Sm3+离子的4G_5/26H_J/2〖KG0.4mm〗(J=5,7,9,11)跃迁,最强峰位于611 nm;在611 nm波长的光激发下,激发峰位于335和407 nm.
    Abstract: Sm3+ doped TiO2 powders were prepared by the sol-gel method, and the properties were characterized. The results indicated that the obtained sample is a mixed phase TiO_2 with anatase and rutile structure. Under 355 nm excitation, TiO2 showed strong orange-red emission, the emission spectra exhibited four emission peaks at 582, 611, 662, and 725 nm, corresponding to 4G_5/26H_J/2〖KG0.2mm〗(J=5, 7, 9, 11) transition of Sm3+, the strongest emission peak is at 611 nm; The excitation spectra of TiO2〖KG-1mm〗∶〖KG-1mm〗Sm3+ powders are composed of two excitation peaks at 335 and 407 nm under 611 nm excitation.
