X射线辐照诱导室温持续光谱烧孔（PSHB）在Eu 3+掺杂硼酸盐玻璃在惰性气氛下熔化。缺陷是由X射线辐照形成的，这些缺陷，特别是玻璃中稀土离子附近的电子捕获中心，是PSHB的原因。在燃烧的光照射下，电子从这些缺陷中释放出来。通过捕获这些电子的Eu3+到Eu2+的光还原导致形成持久的光谱空穴。
Irradiation of x-rays has induced room-temperature persistent spectral hole burning (PSHB) in Eu3+-doped borate glasses melted under an inert atmosphere. Defects were formed by x-ray irradiation and these defects, especially electron trapping centers near rare-earth ions in glasses, were responsible for the PSHB. Electrons were released from these defects upon irradiation of a burning light. Photoreduction of Eu3+ to Eu2+ by trapping these electrons resulted in the formation of persistent spectral holes.
