A slow release of the hole trapped at Dy followed by recombination
at Eu then leads to the luminescence that may persist throughout the night. Actually there is no such thing as a hole left behind in the 4f state because the electron excited to the 5d state is still bonded to Eu2+. One may only speak of a hole after the electron has completely escaped to the conduction band.Illuminating the phosphor by shorter than 390nm wavelength light, i.e. daylight, brings the
electron from Eu2+ inside the conduction band of SrAl2O4.

被Dy所俘获的空穴缓慢的热释放，随后在Eu复合并引起发光，这种发光可能持续整个夜晚。实际上4f态并没有产生空穴，因为被激发到5d态的电子仍然被Eu2+束缚。只有当电子完全逃逸到导带时才可以说有空穴。用波长比390 nm短的光，比如日光照射磷光体，会使电子从Eu2+进入SrAl2O4的导带。

被Dy所俘获的空穴首先缓慢释热，随后在Eu复合并引起发光，这种发光有可能持续一夜。实际上4f态并没有产生空穴，因为被激发到5d态的电子仍然被Eu2+束缚。只有当电子完全逃逸到导带时才可以说有空穴。用波长小于390nm的光（即日光）来照射磷光体，会使电子从Eu2+进入SrAl2O4的导带。
你翻译的很好，只做少许改动。这篇文章好专业哟。
