| 英文摘要 | spectroscopic property and energy transfer processes of singly doped and codoped er3+ and nd3+ fluoroaluminate glasses with low phosphate content are systematically analyzed. the absorption spectra of these glasses are tested, and the judd-ofelt (j-o) and radiative parameters are discussed based on j-o theory and the parameters changes substantially because of the other codoping ions. as for nd3+: the main emission bands at 0.9 and 1.05 mu m decrease in the codoped sample under the excitation of an 800 nm laser diode from the emission spectra because the er3+: i-4(11/2) level reduces the nd3+: i-4(3/2) level effectively through the energy transfer process nd3+: f-4(3/2) -> er3+: i-4(11/2). for er3+, the emission at 1.5 mu m is restrained by codoping with nd3+ ions from the energy transfer process er3+: i-4(13/2) -> nd3+: i-4(15/2). the emission at 2.7 mu m is enhanced because the nd3+ ions deplete the lower level and exert a positive effect on the upper laser level. the microparameters of the energy transfer between the er3+ and nd3+ ions are calculated and discussed using forster-dexter theory. the energy transfer efficiencies of the nd3+: f-4(3/2) to the er3+: i-4(11/2) and the er3+: i-4(13/2) to the nd3+: i-4(15/2) are 28.8% and 74.5%, respectively. these results indicate that nd3+ can be an efficient sensitizer for er3+ to obtain mid-infrared (mid-ir),emission and the codoped er3+/nd3+ fluoroaluminate glass with low phosphate content is suitable to be used as the fiber optical gain media for 2.7 mu m laser generation.
