基于成分为 TeO2-WO3-Nb2O5-Na2O-Al2O3-Er2O3-Yb2O3 的玻璃的亚碲酸盐纤维是使用 Heathway 拉丝塔通过管棒技术制造的。研究了 Er3+/Yb3+ 共掺杂亚碲酸盐玻璃纤维在 980 nm 激发下的上转换发光。与Er3+ 掺杂的亚碲酸盐光纤相比，Er3+/Yb3+ 共掺杂的亚碲酸盐光纤表现出高效的上转换过程。讨论了泵浦功率相关的强度，这表明上转换过程涉及两个光子。
The tellurite fibers based on glasses with the composition TeO2–WO3–Nb2O5–Na2O–Al2O3–Er2O3–Yb2O3were fabricated by the rod-in-tube technique using a Heathway drawing tower. The upconversion luminescence of Er3+/Yb3+codoped tellurite glass fibers under 980 nm excitation were investigated. The Er3+/Yb3+co-doped tellurite fibers show an efficient up-conversion process in comparison with the Er3+-doped tellurite fibers. The pump power dependent intensities were discussed, which showed that two photons are involved in the upconversion process.
