- W2386479000 abstract "Trivalent erbium doped glasses are attracting extensive interest due to its potential application in various optical devices such as optical communication, display and lasers. In this paper, the preparation and the infrared luminescent properties of some erbium doped oxide glasses were reported. High erbium doped three multicomponent oxide glasses, B2O3-SiO2, Al2O3-SiO2 and Li2O3-A12O3-SiO2 were fabricated by the technique of high-temperature melting. The infrared emission spectra of erbium in the glasses were measured under the excitation of a 488nm argon ion laser. The influence of the host composition and the erbium-con- centration on infrared luminescent property at 1 .5μm was studied. The results indicate that the emission in- tensity varies remarkably in different hosts. Among the glasses, the emission of erbium in the B2O3-SiO2 glass is strongest, while that in the A12O3-SiO2-CdO glass is the weakest. In addition, the emission intensity of B2O3-SiO2 glass doped with erbium increases almost linearly with the erbium concentration, which is favo- rable for luminous material. In all the glasses, the emission intensity at 1. 5μm increases with the erbium concentration, indicating that the concentration-quenching effect is small as the erbium concentration is low- er than 2wt %. Among the three glasses, the Er3 + Li2O-Al2O3-SiO2 one has a widest emission band at 1.5μm. The global line width of erbium in this glass is as wide as 61. 1nm due to the disordered local struc- ture surrounding the erbium ions. Therefore, it is expected to be a deal glass for optical waveguide ampli- fiers. By contrast to the components of the three glasses, it can be concluded that the global line width of er- bium is probably broadened due to the co-doping of Li2O in the A12O3-SiO2 glass, although the detail origin is not clear." @default.
