Persistent spectral hole burning has been observed at 77 K, 180 K, and room temperature for Eu(3+) in sodium aluminosilicate glass melted under a reducing atmosphere. In particular, room-temperature persistent spectral hole burning is reported for the first time to our knowledge in Eu(3+) -doped materials. The persistent hole is accompanied by no antiholes and lasts for 1 h at least. The thermal stability of the hole is greater than that of a persistent hole burned for Eu(3+) in sodium aluminosilicate glass melted in air.
在还原气氛下熔化的硅铝酸钠玻璃中，已观察到 Eu(3+) 在 77 K、180 K 和室温下存在持久光谱烧孔现象。据我们所知，首次报道了 Eu(3+) 掺杂材料中的室温持久光谱烧孔现象。该持久烧孔没有伴生反烧孔，且至少持续 1 小时。此烧孔的热稳定性高于在空气中熔化的硅铝酸钠玻璃中 Eu(3+) 所形成的持久烧孔。
