Abstract

Samarium L_III x-ray absorption fine structure spectra for both Sm²⁺ and Sm³⁺-doped (100-X)B₂O₃ XNa₂O (X= 10,15,20) glasses and both Sm²⁺ and Sm³⁺-doped 85B₂O₃ (15-X)Al₂O₃ XNa₂O (X= 5,10) glasses were measured using synchrotron radiation. The oxygen coordination number of samarium in Sm²⁺-doped glass is different from that of the Sm³⁺-doped glass with the same composition while the nearest neighbor Sm-O distances are closely the same. The change of coordination numbers with alkali or aluminum addition was related to the variation of the optical hole width of Sm²⁺-doped glasses.
