Traditional vanadate glasses are known to be totally black (see inset Figure), while their crystal counterparts are promising laser materials due to their large stimulated-emission cross-section. In this work, a novel transparent vanadate glass (see main Figure) is realized for the first time. Furthermore, when doped with neodymium, its large stimulated-emission cross-section and low phonon energy demonstrate potential to be utilized in optical applications, especially in laser-related fiber optics.
