| 英文摘要 | this study presents the luminescent properties of yb3+/tm3+ co-dopant ions inside a new host glass based on bismuth germanates. judd ofelt intense parameters, radiative transition rate, radiative lifetime, and branching ratios of tm3+ in the present glass are calculated based on the absorption spectrum. a strong 1.8 gm emission was observed in the yb3+/tm3+ co-doped bismuth germanate glass upon the excitation of a conventional 980 nm laser diode. using a spectral overlap model, the micro parameter for direct energy transfer from yb3+ ions to tm3+ ions (c-da) was found to be almost 30 times larger than the back energy transfer from tm3+ ions to yb3+ ions (c-ad). the linear dependence of energy transfer probability on the co-dopant concentration exhibits that the energy transfer is assisted by energy migration among donor ions. the large energy transfer efficiency (89%) indicates that the yb3+/tm3+ co-doped bismuth germanate glass is a good candidate for the 1.8 gm laser. crown copyright (c) 2013 published by elsevier ltd and techna group s.r.l. all rights reserved. |
