Recently, we reported on the development of a series of Dy-doped organic molecular crystals (with analogous material properties to energetic organic molecular crystals) for use as two-color thermometry phosphors in thermometric imaging of heterogeneous materials under shock compression. In this study, we demonstrate thermometric imaging of one of these phosphors—Dy:Y(acac) $$_3$$ (DPEPO)—under pulsed laser heating and compare its performance to the well-known two-color thermometry phosphor Dy:YAG. Based on these comparisons, we indirectly confirm that Dy:Y(acac) $$_3$$ (DPEPO) is a suitable two-color thermometric phosphor for shock compression experiments.

脉冲激光加热过程中异质材料的双色测温成像

最近，我们报道了一系列 Dy 掺杂的有机分子晶体（具有与高能有机分子晶体类似的材料特性）的开发，用作双色测温荧光粉，用于冲击压缩下异质材料的测温成像。在这项研究中，我们展示了其中一种磷光体——Dy:Y(acac) $$_3$$ (DPEPO)——在脉冲激光加热下的测温成像，并将其性能与众所周知的双色测温磷光体 Dy:YAG 进行比较. 基于这些比较，我们间接证实了 Dy:Y(acac) $$_3$$ (DPEPO) 是一种适用于冲击压缩实验的双色测温荧光粉。
