Localized micro-structure and luminescence property are modified in Ag+-doped phosphate glass with high repetition rate femtosecond laser pulses. Confocal fluorescence spectra show that the luminescence intensity due to fs-laser induced Ag0gradually increases and then decreases with the decreasing distance from the center of the laser-affected zone. In the inner structure, the intensity ratio of two Raman bands at 708 cm- 1and 1210 cm- 1decreases with the more close to the center of the laser-affected zone. A possible mechanism is proposed to explain the observed phenomena. © 2013 Elsevier B.V. All rights reserved.
