| 中文摘要 | the absorption spectra and upconversion fluorescence spectra of er3+/-yb3+-codoped natrium-gallium-germanium-bismuth glasses are measured and investigated. the intense green (533 and 549 nm) and red (672 nm) emission bands were simultaneously observed at room temperature. the quadratic dependence of the green and red emission on excitation power indicates that the two-photon absorption processes occur. the influence of ga2c3 on upconversion intensity is investigated. the intensity of green emissions increases slowly with increasing ga2o3 content, while the intensity of red emission increases significantly. the possible upconversion mechanisms for these glasses have also been discussed. the maximum phonon energy of the glasses determined based on the infrared (ir) spectral analysis is as low as 740 cm(-1). the studies indicate that bi2o3-geo2-ga2o3-na2o glasses may be potential materials for developing upconversion optical devices (c) 2006 published by elsevier b.v. |
