| 英文摘要 | in present study, we investigated the emissions from visible to mid-infrared and energy transfer processes in er3+/yb3+ co-doped germanate-gallate-bismuthate (bgg) glasses. larger absorption cross-section of yb3+ ions (7.5 x 10(-21) cm(2)) and enhanced up-conversion, near-infrared and mid-infrared emissions indicate that the introduced sensitized yb3+ ions can efficiently absorb and transfer pumping energy (980 nm) to activate the er3+ ions. the intensity of 2.7 mu m emission in er3+/yb3+ co-doped samples is about 3 times higher than that of er3+ singly doped sample. but, the intensity of 2.7 mu m emission decreases with excessive yb3+ ions. the optimized ratio of er3+ and yb3+ ions for 2.7 mu m emission is 1.0:0.2 in this bgg glasses. large emission cross-section sigma(e) (-13 x 10(-21) cm(2) and -9.57 x 10(-21) cm(2) for 2.7 mu m and 1.5 mu m emissions, respectively) is obtained in er3+/yb3+ co-doped bgg glasses. according to absorption and emission spectra, energy transfer processes between yb3+ and er3+ ions were proposed and main reason for increased up-conversion is the strong excited state absorption (esa) from excited er3+ ions at i-4(11/2) and i-4(13/2) levels. therefore, high pumping efficiency, intense emissions, large emission cross-section of 2.7 mu m and 1.5 mu m emissions and efficient energy transfer processes in this er3+/yb3+ co-doped bgg glasses hints its potential applications in laser materials, especially in 2.7 mu m wavelength.
