热成像磷光体的寿命需要足够短以分辨温度时间尺度，并且足够长以由相应的检测器适当地分辨。到目前为止，还没有一种热成像磷光体，其对于使用高速照相机的内燃机内部的二维温度测量表现出足够的温度寿命特性。因此，本研究提出了用于此目的的材料Gd3Ga5O12：Cr。的发射光谱和温度寿命特性进行了测定，寿命被证明是独立的组成和周围的气相的绝对压力。
The lifetime of thermographic phosphors needs to be short enough to resolve the temperature time scales and long enough to be properly resolved by the respective detector. Up until now, there has not been a thermographic phosphor that exhibits an adequate temperature lifetime characteristic for two-dimensional thermometry inside internal combustion engines using high speed cameras. Hence, this study suggests the material Gd3Ga5O12:Cr for this purpose. The emission spectra and the temperature lifetime characteristics were determined and the lifetime is shown to be independent of the composition and the absolute pressure of the surrounding gas phase.
