英文摘要	Er3+/yb3+-codoped strontium-lead-bismuth glasses for developing potential upconversion lasers have been fabricated and characterized. the optimal yb3+ doping content was investigated in the glasses with different yb3+-er3+ concentration ratios and the optimal yb3+-er3+ concentration ratio is 5:1. under 975-nm excitation, intense green and red emissions centered at 525, 546, and 657 rum, corresponding to the transitions h-2(11/2) --> 4i(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 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.
