Effect of GeO2 additive on fluorescence intensity enhancement in bismuth-doped silica glass

This paper investigates the effect of different amounts of germanium oxide additive on incremental changes of fluorescence intensity of bismuth-doped silica glass (BiSG). The results indicate that the effect is more notable at a low Bi

additive effectively generates peculiar luminescent centers and increases the potential applications of bismuth-doped silica glass.
