Abstract
Ag+-doped 70B2O3-30M2O, 70B2O3-30M'O, and 70B2O3-15M2O-15M'O glasses (M: Li, Na, and K, M': Ca, Sr, and Ba) were prepared by the melt-quenching method, and their fluorescence and excitation spectra were measured. The fluorescence band due to the 4d95s1→4d10 transition of Ag+ appeared in the UV region. In each glass system, the wavelength of the fluorescence red-shifted with increasing of the basicity of the host glass. Therefore, it was found that Ag+ ions were solved into the site of each glass system, and that the crystal field strengthened with increasing of the basicity of the host glass.
