FIG. 2.

(a) Emission fluorescence spectra obtained for an irradiated local area of a SBN glass doped with 5% of using an Ar laser and increasing the laser power beam from 400 to 1500 mW. The arrow shows the increasing direction of energy. (b) Integrated area of the two intensity peaks obtained in the emission fluorescence spectra while increasing the laser power beam until 1500 mW. The triangle symbols correspond to the area at 880 nm, whereas the square symbols, to the 810 nm.

FIG. 3.

Intensity ratio between 810 and 880 nm emission bands as a function of the temperature. The solid line represents the theory values and the triangle symbols correspond to the experimental result.

Image of FIG. 4.
FIG. 4.

Emission fluorescence spectra obtained after the irradiation process by using an Ar laser at low power inside (solid line) and outside the irradiated area (dot line). The dashed line shows the emission of the GC sample.

FIG. 5.

(a) fluorescence decays for -solution glass and GC with a 5% doping concentration for a wavelength of 880 nm. (b) fluorescence decays for -solution GC with a 5% doping concentration for two different wavelengths, 880 and 900 nm.

Image of FIG. 6.
FIG. 6.

Emission band of the transition obtained from the decay curves inside the irradiated area. The solid line shows the experimental result and the dashed line gives the emission corresponding to the GC phase.
