本文报道了掺钬镱离子的氟氧化物玻璃陶瓷的一级和二级红外量子剪裁的比较研究.研究发现当5G5能级到5S2能级及之间的能级被激发的时候,大多数的粒子数容易无辐射弛豫到(5F45S2)能级.在(5F45S2)能级, 由很强的ETr7-ETaYb{5F4(Ho)5I6(Ho), 2F7/2(Yb)2F5/2(Yb)}交叉能量传递渠道, 导致Ho3+离子的粒子数被无损耗的交叉能量传递到5I6能级, 同时Yb3+离子从基态2F7/2能级被激发到2F5/2能级,它导致了两个能被晶体硅有效吸收的红外光子, 即一个(1153 nm, 1188 nm)的红外光子和另一个(973.0 nm, 1002.0 nm) 的红外光子,因此出现了显著的双光子一级红外量子剪裁. 最后,该文计算了Ho(0.5)Yb(1):FOV和Ho(0.5)Yb(10.5):FOV的交叉能量传递效率为tr, 1% Yb(5F45S2)=29.2%, tr,10.5% Yb(5F45S2)=99.2%和它们的共合作能量传递效率为tr, 1% Yb(5F3)=4.18%, tr, 10.5% Yb(5F3)=75.3%;而它们的双光子量子剪裁效率的理论上限值依次为CR, 1% Yb(5F45S2)=129.2%, CR, 10.5% Yb(5F45S2)=199.2% 和CO, 1% Yb(5F3)=104.18%, CO, 10.5% Yb(5F3)=175.3%.因此发现了一级红外量子剪裁有比二级红外量子剪裁高较多的概率.该项研究对太阳能电池效率的提高很有意义.

Infrared quantum cutting is an international hot research field nowadays. Comparitive research between first-order and second-order quantum cutting of Ho3+ Yb3+ doped oxyfluoride vitroceramics is reported in present paper. It is found that most population can easily non-radiativly relax to (5F45S2) energy level when the energy levels between 5G5 and 5S2 are excited. For (5F45S2) level, the population of Ho3+ ion can be cross-transferred to 5I6 level by strong ETr7-ETaYb {5F4(Ho) 5I6 (Ho), 2F7/2(Yb) 2F5/2(Yb)} cross energy transfer passage; meanwhile, Yb3+ ion is excited to 2F5/2 level from 2F7/2 ground state. It results in the two infrared photons which can be absorbed by crystal Si, that is, one is (1153 nm, 1188 nm) infrared photon and the other is (973.0 nm, 1002.0 nm) infrared photon. Therefore, it results in two-photon first-order infrared quantum cutting. Finally, the cross energy transfer efficiency tr, 1%Yb(5F45S2)=29.2%, tr, 10.5%Yb(5F45S2)=99.2%. and cooperative energy transfer efficiency tr, 1%Yb(5F3)=4.18%, tr, 10.5%Yb(5F3)=75.3% of Ho(0.5)Yb(1):FOV and Ho(0.5)Yb(10.5):FOV are calculated. Their quantum efficiency up-limits of two-photon quantum cutting are CR, 1%Yb(5F45S2)=129.2%, CR, 10.5% Yb(5F45S2)=199.2 and CO, 1%Yb(5F3)=104.18%, CO, 10.5% Yb(5F3)=175.3% respectively. That is to say, the probability of first-order infrared quantum cutting is larger than that of second-order infrared quantum cutting. The present research is of significance for enhancing solar cell efficiency.-
