Er³⁺ to Eu³⁺ energy-transfer and frequency upconversion in PbGeO₃:PbF₂:CdF₂ glass are reported. Emission spectra excited at 980 nm was obtained for Er³⁺-doped samples, while Eu³⁺ emissions only occurred for double-doped (Er³⁺/Eu³⁺) or triple-doped (Yb³⁺/Er³⁺/Eu³⁺) samples. Codoped samples’ spectra exhibit bands around 520 (²H_{11/2 –}⁴I_15/2), 545 (⁴S_{3/2 –}⁴I_15/2), 590 (⁵D₀ – ⁷F₁), 610 (⁵D₀ – ⁷F₂), 660 (⁴F_{9/2 –}⁴I_15/2) and 700 (⁵D₀ – ⁷F₄) nm. The Er³⁺ green emissions’ lifetimes were examined as a function of Eu³⁺ content evidencing Er³⁺-to-Eu³⁺ energy-transfer. The addition of Yb³⁺ enhanced the Eu³⁺ ions’ emissions suggesting potential application for upconversion-based white light phosphor.

报道了在PbGeO ₃：PbF ₂：CdF ₂玻璃中Er ³⁺到Eu ^3+的能量转移和频率上转换。对于掺Er ^3+的样品，获得了在980 nm处激发的发射光谱，而Eu ³⁺发射仅发生于双掺杂（Er ³⁺ / Eu ³⁺）或三掺杂（Yb ³⁺ / Er ³⁺ / Eu ³⁺）个样本。共掺杂样品的光谱显示出约520（² H _{11/2 –} ⁴ I _15/2），545（⁴ S _{3/2 –} ⁴ I _{15/2）的能带。}），590（⁵ D ₀ – ⁷ F ₁），610（⁵ D ₀ – ⁷ F ₂），660（⁴ F _{9/2 –} ⁴ I _15/2）和700（⁵ D ₀ – ⁷ F ₄）nm 。急诊室³⁺绿色排放寿命检查作为铕的功能³⁺内容证明尔³⁺ -to-的Eu ³⁺能量转移。Yb ^3+的添加增强了Eu ³⁺ 离子的发射暗示了基于上转换的白光磷光体的潜在应用。
