Temperature-dependent diffuse reflectance measurements on Cr-doped -alumina monoliths have been performed using supercontinuum-laser illumination and -laser heating. These measurements have been interpreted using an extended Kubelka-Munk (K-M) model describing diffuse-light propagation in highly scattering and fluorescent media to assess the temperature dependence of fluorescence quantum efficiency. Analysis of experimental results has provided a qualitative understanding of the temperature-dependent conditions for model applicability and also suggests methods for using supercontinuum-laser diffuse reflectance spectroscopy for detection of unknown fluorescent dopants.
利用超连续激光照明和激光加热对掺铬氧化铝整体材料进行了温度相关的漫反射测量。这些测量结果已通过扩展的库贝尔卡-蒙克（K-M）模型进行解释，该模型描述了漫射光在高散射和荧光介质中的传播，以评估荧光量子效率的温度依赖性。对实验结果的分析提供了对模型适用性的温度相关条件的定性理解，还提出了使用超连续激光漫反射光谱法检测未知荧光掺杂剂的方法。
