We demonstrate a method to manufacture Er³⁺/Yb³⁺ co-doped phosphosilicate glass by the digital light processing (DLP) 3D printing based on sol-gel technology. The sol-gel technology was used to fabricate the rare earth ions doped photocurable printing ink to achieve excellent fluidity, tunable composition and uniform component distribution. Following photopolymerization of 3D printing, the parts underwent ageing and sintering at 1050 °C, which is much lower than conventional high temperature melting method (~1700 °C). To the best of our knowledge, this is the first time that rare earth ion doped multicomponent glass has been fabricated by 3D printing based on sol-gel technology. This method combined with fiber drawing technology provides a novel way to fabricate the rare earth ions doped glass fiber.

我们演示了一种制造Er ³⁺ / Yb ^3+的方法通过基于溶胶凝胶技术的数字光处理（DLP）3D打印共掺杂的磷硅酸盐玻璃。溶胶-凝胶技术用于制造掺有稀土离子的光固化印刷油墨，以实现出色的流动性，可调的组成和均匀的成分分布。经过3D打印的光聚合后，零件在1050°C下进行老化和烧结，这比常规的高温熔化方法（〜1700°C）低得多。据我们所知，这是首次通过基于溶胶-凝胶技术的3D打印制造掺杂稀土离子的多组分玻璃。该方法与纤维拉伸技术相结合，为掺杂稀土离子的玻璃纤维的制备提供了一种新颖的方法。
