| 1 | Valence Change and Luminescence of Divalent Samarium in Strontium Borates显示文摘The valence change of samarium from trivalent to divalent state in strontium borates (SrB6O10)prepared in air was observed. The high resolution spectra of Sm2+ in matrix were studied between 10 K and 300 K. The results showed that three crystallographic sites for Sm2+ were available in the host. Energy transfer among these sites was possible. The vibronic transition of 5D0-7F0 of Sm2+ was studied at room temperature and the Huang-Rhys factor S was calculated. Due to the thermal population, 5D1 -7F0 transition at room temperature was | Qinghua ZENG Zhiwu PEI Shubing WANG and Qiang SU(Laboratory of Rare Earth Chemistry and Physics, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022, China) To whom correspondence should be addressedE-mail: zengqh@ns. | 1999 | Journal of Materials Science & Technology1999，15，5： | 1 |
