Abstract

The optical spectroscopy and the decay kinetics of samples with composition Sr₃Yb(PO₄)₃, Sr₃Y_0.98Yb_0.02(PO₄)₃, Sr₃Y_0.98Er_0.02(PO₄)₃ and Sr₃Yb_0.98Er_0.02(PO₄)₃ have been studied at room temperature. The presence of efficient energy transfer and migration processes has been clearly evidenced in the Sr₃Yb(PO₄)₃ and Sr₃Yb_0.98Er_0.02(PO₄)₃ materials, giving rise to strong visible upconversion upon excitation in the spectral region around 1 μm in the latter material. The strong anti-Stokes emission is connected to fast migration in the ²F_5/2 level of Yb³⁺, due to the inefficient concentration quenching for this ion. In this class of materials, the upconversion processes could be optimized even in the presence of high concentrations of the Yb³⁺ sensitizer.

导致镱富集的 Sr3Yb0.98Er0.02(PO4)3 eulytite 中发生强烈的近红外-红外上转换的能量转移过程

我们在室温下研究了 Sr3Yb(PO4)3、Sr3Y0.98Yb0.02(PO4)3、Sr3Y0.98Er0.02(PO4)3 和 Sr3Yb0.98Er0.02(PO4)3 样品的光学光谱和衰变动力学。在 Sr3Yb（PO4）3 和 Sr3Yb0.98Er0.02（PO4）3 材料中清楚地证明了高效能量转移和迁移过程的存在，后者在 1 μm 左右的光谱区受到激发后产生了强烈的可见光上转换。强烈的反斯托克斯发射与 Yb3+ 2F5/2 电平的快速迁移有关，原因是该离子的浓度淬火效率较低。在这一类材料中，即使存在高浓度的 Yb3+ 增感剂，也能优化上转换过程。
