摘要: The infrared quantum cutting of oxyfluoride nanophase vitroceramics Tb(0.7)Yb(3):FOV has been studied in the present paper. The actual quantum cutting efficiency formula calculated from integral fluorescence intensity is extended to the case of Tb(0.7)Yb(3):FOV. The visible and the infrared fluorescence spectra and their integral fluorescence intensities are measured from static fluorescence experiment. Lifetime curve is measured from dynamic fluorescence experiment. It is found that the total actual quantum cutting efficiency η of the excited 5D4 level is about 93.7%, and that of excited (5D3, 5G6) levels is 93.5%. It is also found that the total theoretical quantum cutting efficiency upper limit ηx%Yb of the 485.5 nm excited <5D4 level is about 121.7%, and that of 378.5 nm excited (5D3, 5G6) levels is 137.2%.

Abstract: The infrared quantum cutting of oxyfluoride nanophase vitroceramics Tb(0.7)Yb(3):FOV has been studied in the present paper. The actual quantum cutting efficiency formula calculated from integral fluorescence  intensity is extended to the case of Tb(0.7)Yb(3):FOV. The visible and the infrared fluorescence spectra and their integral fluorescence intensities are measured from static fluorescence experiment. Lifetime curve is measured  from dynamic fluorescence experiment. It is found that the total actual quantum cutting efficiency $\eta $ of the excited $^{5}$D$_{4}$ level is about 93.7%, and that of excited ($^{5}$D$_{3}$, $^{5}$G$_{6})$ levels is  93.5%. It is also found that the total theoretical quantum cutting efficiency upper limit $\eta _{x\%\rm Yb} $ of the 485.5 nm excited $^{5}$D$_{4}$ level is about 121.7%, and that of 378.5 nm excited ($^{5}$D$_{3}$,  $^{5}$G$_{6})$ levels is 137.2%.
