The development of the stereolithography technique for the additive manufacturing of silica glass has brought revolutionary change in glass manufacturing. Here, we demonstrate the fabrication of 3D luminescent transparent glass parts manufactured by the stereolithographic technique together with solution impregnation and high temperature sintering. Prefabricated glass parts with nanopores were prepared by the stereolithography technique and debinded and pre-sintered at first. To functionalize the additive manufactured glass with photoluminescence, Eu, Tb and Ce ions were doped with a solution impregnation method and further sintered at high temperature. The photoluminescence from these rare earth ions in the blue, cyan and red spectral region can be facilely generated by illumination with a 254 nm UV lamp. Furthermore, we developed a space-selective doping method that enables the doping of different ions in different parts of a silica glass in a space-selective fashion, resulting in a multicolor luminescent glass object giving distinguishable luminescence from each part.
用于二氧化硅玻璃增材制造的立体光刻技术的发展给玻璃制造带来了革命性的变化。在此，我们展示了通过立体光刻技术结合溶液浸渍和高温烧结制造的3D发光透明玻璃部件。首先通过立体光刻技术制备具有纳米孔的预制玻璃部件，然后进行脱脂和预烧结。为了使增材制造的玻璃具有光致发光功能，采用溶液浸渍法掺杂Eu、Tb和Ce离子，并进一步高温烧结。用254nm紫外灯照射可轻松产生这些稀土离子在蓝色、青色和红色光谱区域的光致发光。此外，我们开发了一种空间选择性掺杂方法，能够以空间选择性方式在二氧化硅玻璃的不同部分掺杂不同的离子，从而得到一个多色发光玻璃物体，其各部分发出可区分的发光。
