Energy level positions, refractive index values, Judd–Ofelt (JO) intensity parameters, Slater integrals, and spin-orbit coupling parameters are taken from the literature for 27 Dy3+-doped materials (five crystals and 22 glasses). Investigated are only the transitions that are used for the Boltzmann-type luminescence intensity ratio (LIR) thermometers (transitions from the three thermalized levels, 4F9/2, 4I15/2, and 4G11/2 to the ground level). Reduced matrix elements of these three transitions are calculated from the Slater integrals and spin-orbit coupling parameters and they are compared to the most frequently used values from Carnall's tables. The comparison of JO parameters shows the smaller variation of the Ω6, related to rigidity, in crystal hosts than in glasses, and the opposite was observed for the Ω2,4 parameters. LIR performances are simulated by the JO thermometric model for each material by the conventional LIR and the LIR that exploits the third thermalized level. The comparison of the predicted figures of merit in luminescence thermometry reveals the most promising thermometric Dy3+ doped crystals and glasses.

使用 Judd-Ofelt 理论对基于 Dy3+ 的玻尔兹曼温度计的性能进行建模
能级位置、折射率值、Judd-Ofelt (JO) 强度参数、Slater 积分和自旋轨道耦合参数取自 27 种 Dy 3+掺杂材料（5 种晶体和 22 种玻璃）的文献。仅研究了用于玻尔兹曼型发光强度比 (LIR) 温度计的跃迁（从三个热化水平4 F 9/2、4 I 15/2和4 G 11/2的跃迁到地面）。这三个跃迁的简化矩阵元素是根据 Slater 积分和自旋轨道耦合参数计算的，并将它们与 Carnall 表中最常用的值进行比较。JO 参数的比较表明，与玻璃相比，晶体主体中与刚性相关的 Ω 6变化较小，而对于 Ω 2,4参数观察到相反的情况。LIR 性能由 JO 测温模型模拟每种材料的常规 LIR 和利用第三热化水平的 LIR。发光测温中预测的品质因数的比较揭示了最有希望的测温 Dy 3+掺杂晶体和玻璃。
