Abstract

Photoreduction of samarium-doped BaCl 2 -modified aluminofluoride glass by femtosecond laser irradiation and x-ray irradiation were investigated. Photoluminescence of samarium ions indicated that photoreduction of Sm 3 + Sm 2 + efficiently occurred in glass samples containing more than 5 mol . % BaCl 2 after femtosecond laser irradiation, while dramatic change was not observed by x-ray irradiation. Transmission electron microscope results revealed that BaCl 2 nanophases only precipitated from glass matrix with a high BaCl 2 content by focusing femtosecond laser irradiation. Samarium ions were selectively incorporated into the precipitated nanophases, resulting in the enhancement of Sm 3 + photoreduction under lower laser power.
