关于磷光体测温，材料Y3 Al 5 O 12：Eu（YAG：Eu）和YAlO 3：Eu（雅普：Eu）被合成和表征，以取代常用的热敏磷光体Y2 O3：Eu，其温度敏感发光寿命对周围气相的氧浓度表现出强烈的且最经常不期望的交叉敏感性。合成的详细概述和晶体结构，其特征在于通过X-射线衍射。在第二步中，确定脉冲UV激光激发后的发光性质。在这种情况下，发射光谱和温度寿命特性进行了监测。Y3 Al 5 O 12：Eu和YAlO 3：Eu的温度敏感范围分别为1000 K-1470 K和850 K-1300 K。与Y2 O3：Eu相反，这两种材料对周围气相的氧浓度都表现出低得多的交叉灵敏度。
With regard to phosphor thermometry, the materials Y3Al5O12:Eu (YAG:Eu) and YAlO3:Eu (YAP:Eu) were synthesised and characterised in order to substitute the commonly used thermographic phosphor Y2O3:Eu, whose temperature sensitive luminescence lifetime exhibits a strong and most often undesirable cross-sensitivity to the oxygen concentration of the surrounding gas phase. The synthesis is outlined in detail and the crystallographic structure was characterised by X-ray diffraction. In a second step, the luminescence properties following pulsed UV laser excitation were determined. In this context, the emission spectra and the temperature lifetime characteristics were monitored. For Y3Al5O12:Eu and YAlO3:Eu, temperature sensitive ranges of 1000 K–1470 K and 850 K–1300 K were identified. Contrary to Y2O3:Eu, both materials do show much lower cross-sensitivities to the oxygen concentration of the surrounding gas phase.
