本文报道了在MgO：Mn ~（2+）纳米晶体中观察到的一对尖锐的零声子线，它们同时出现在光致发光中。我们提出了一个原因，为什么这些线还没有被观察到在系统中的问题，即使在散装材料，但出现在燃烧合成的纳米晶体。非常尖锐的零声子线的激发的容易性使得我们的发现对于光学纳米器件应用具有吸引力。
We report the observation of a pair of sharp zero-phonon lines in MgO:Mn2+ nanocrystals, which appear simultaneously in photoluminescence. We suggest a reason why these lines have not yet been observed in the system in question even in the bulk material, but appear in nanocrystals synthesized by combustion. The easiness of the excitation of extremely sharp zero-phonon lines makes our finding attractive for optical nanodevice applications.
