| 中文摘要 | er3+-doped lithium-barium-lead-bismuth glass for developing upconversion lasers has been fabricated and characterized. the judd-ofelt intensity parameters omega(t) (t = 2, 4, 6), calculated based on the experimental absorption spectrum and judd-ofelt theory, were found to be omega(2) = 3.05 x 10(-20) cm(2), omega(4) = 0.95 x 10(-20) cm(2), and omega(6) = 0.39 x 10(-20) cm(2). under 975 nm excitation, intense green and red emissions centered at 525, 546, and 657 nm, corresponding to the transitions h-2(11/2) -> i-4(15/2), s-4(3/2) -> i-4(15/2), and f-4(9/2) -> i-4(15/2), respectively, were observed at room temperature. the upconversion mechanisms are discussed based on the energy matching and quadratic dependence on excitation power, and the dominant mechanisms are excited state absorption and energy transfer upconversion for the green and red emissions. the long-lived i-4(11/2) level is supposed to serve as the intermediate state responsible for the intense upconversion processes. the intense upconversion luminescence of er3+-doped lithium-barium-lead-bismuth glass may be a potentially useful material for developing upconversion optical devices.
