中文摘要	infrared-to-visible upconversion fluorescence of er(3+)/yb(3+) co-doped lithium-strontium-lead-bismuth (lspb) glasses for developing potential upconversion lasers has been studied under 975-nm excitation. based on the results of energy transfer efficiency and upconversion spectra, the optimal yb(3+)-er(3+) concentration ratio is found to be 5:1. intense green and red emissions centered at 525, 546, and 657 nm, corresponding to the transitions 2h_(11/2)-->4i_(15/2), 4s_(3/2)-->4i_(15/2), and 4f_(9/2)-->4i_(15/2), respectively, were observed. the quadratic dependence of the 525-, 546-, and 657-nm emissions on excitation power indicates that a two-photon absorption process occurs under 975-nm excitation. the high-populated 4i_(11/2) level is supposed to serve as the intermediate state responsible for the upconversion processes. the intense upconversion luminescence of er(3+)/yb(3+) co-doped lspb glasses may be a potentially useful material for developing upconversion optical devices.
