Abstract： Fluorescence of Tm3+/Er3+ codoped bismuth-silica (BS) glasses and the sensitization of Ce3+ are investigated. It shows that Ce3+ codoping with Tm3+/Er3+ in BS glasses results in a quenching of Tm3+ ion emission from 3+F4 to the 3+H4 level. Consequently, the 1.47μm emission occurs after the population inversion between the 3+H4 and 3+F4 levels. Furthermore, the codoped glasses show the broad emission spectra over the whole S and C bands with full-width at half-maximum (FWHM) up to about 119nm, as it combines 1.55μm emission band of Er3+ with 1.47μm emission band of Tm3+ under 800nm excitation.
