摘要：

Infrared to visible frequency upconversion in an erbium-doped lanthanum-oxide chalcogenide glass excited at 1.06 mu m, is reported for the first time. Intense green upconversion emission lines at 525 and 550 nm of the thermally coupled excited State levels H-2(11/2) and S-4(3/2), respectively, is observed. A much lower intensity emission band around 670 nm corresponding to the F-4(9/2)-I-4(15/2) transition, is also observed. Two-photon absorption and phonon-assisted energy transfer account for the upconversion excitation mechanism. (C) 1998 Elsevier Science B.V. All rights reserved.
