Pressure-and temperature-dependent luminescence properties of ^(3)F_(3/2)→^(4)I9/2 transition of Nd^(3+):GdTaO_(4) were studied for potential applications in optical *** isolated emission lines corresponding to^(3)F_(3/2)(R2,1)→^(4)I_(9/2)(Z5)transitions,located at 920 and 927 nm under ambient condition,are very sensitive to pressure with coefficients of-15.6 and-14.5 cm^(-1)/GPa determined in a pressure range up to about 9 *** luminescence intensity ratio between the two emission lines exhibits a large dependence with temperature in a range from 80 to 620 K,the corresponding temperature sensitivity at room temperature is similar to that of Nd^(3+):*** advantages,together with the other observed features of high stable position relationship under pressure and low thermal shifts for the two emission lines indicate that Nd^(3+):GdTaO_(4) is a promising candidate to be used as pressure and temperature sensors in the near-infrared spectral range.

为解决现有双氧水生产工艺中甲醇再生树脂不完全而导致树脂更换频率高的问题,通过借助高分辨液质联用、热重分析、傅里叶红外光谱、X线光电子能谱等表征手段分析了双氧水再生工艺中树脂吸附双氧水前后含有的有机杂质及无法完全再生脱附出来的杂质;选用了不同的再生剂对失活树脂进行再生,并通过傅里叶红外变换光谱对再生后树脂进行了表征分析,NaOH溶液处理后失活树脂中属于2甲基环己基醋酸酯的红外特征峰已经完全消失;然后配制了不同浓度的NaOH溶液对失活树脂的再生进行了条件优化,N 2吸脱附测试结果表明,当碱液浓度为0.25 mol/L时,失活树脂的比表面积恢复为575 m^(2)/g,高于甲醇再生后的失活树脂的412 m^(2)/g,其再生效果要优于甲醇再生。
