在Cr3+，Nd3+：Gd3Sc2Ga3O12晶体中的Nd3+离子的近红外发射线上观察到了与R-1，R-2(F-4(3/2))-&Gt；Z(5)(I-4(9/2))和R-1，R-2(F-4(3/2))-&Gt；Z(1)(I-4(9/2))跃迁有关的Nd3+离子的近红外发射线对压力和温度的敏感。前者的线性压力系数分别为-11.3 cm(-1)/Gpa和-8.8 cm(-1)/Gpa，后者在低温范围内表现出较高的热敏感性。因此，这种石榴石晶体可以被认为是一种潜在的光学压力和/或温度传感器，用于高达12 Gpa和低于室温的高压和温度实验，用于金刚石顶压室，并由于多个Cr3+和Nd3+的多个吸收带而被不同的紫外线和可见光商业激光激发。(C)2012年美国光学学会
Hypersensitivity to pressure and temperature is observed in the near-infrared emission lines of the Nd3+ ion in a Cr3+,Nd3+:Gd3Sc2Ga3O12 crystal, associated to the R-1,R-2(F-4(3/2))-> Z(5)(I-4(9/2)) and R-1,R-2(F-4(3/2))-> Z(1)(I-4(9/2)) transitions. The former emissions show large linear pressure coefficients of -11.3 cm(-1)/GPa and -8.8 cm(-1)/GPa, while the latter show high thermal sensitivity in the low temperature range. Thus this garnet crystal can be considered a potential optical pressure and/or temperature sensor in high pressure and temperature experiments up to 12 GPa and below room temperature, used in diamond anvil cells and excited with different UV and visible commercial laser due to the multiple Cr3+ and Nd3+ absorption bands.
