已经观察到氟硼酸铅玻璃中从 Yb3+ 到 Tm3+ 离子的有效非共振能量转移。在 975nm 的 Yb3+ 离子激发下，记录了由于 Tm3+ 离子的 3H4–3H6 跃迁而产生的上转换发光。通过发光衰减分析，一些参数已使用 Inokuti-Hirayama 模型确定。将结果与单掺镱样品记录的结果进行比较，以阐明能量转移过程。
The efficient non-resonant energy transfer from Yb3+to Tm3+ions in lead fluoroborate glasses has been observed. Up-converted luminescence due to3H4–3H6transition of Tm3+ions has been registered under excitation of Yb3+ions at 975nm. From luminescence decay analysis some parameters have been determined using Inokuti–Hirayama model. The results were compared to those recorded with singly Yb-doped samples in order to clarify the energy transfer process.
