摘要

LaCePO4:Dy3+ 的发光实验显示了 275 纳米波长处的激发峰，从而产生了以 475 和 573 纳米波长为中心的可见光区密集峰发射光谱。发射光谱显示了从 4F9/2 到基能态的转变。制备的荧光粉可用于白光发射和热释光剂量计的显示应用。

Photoluminescence and thermoluminescence studies of Dy3+-activated LaCePO4 phosphor

The LaCePO₄:Dy³⁺ luminescence experiments revealed the excitation peak at 275 nm which gives the emission spectra in visible region with intensive peaks centered at 475 and 573 nm. The emission spectra showed the transition from ⁴F_9/2 to the ground energy state. The prepared phosphor may be useful for display applications in white light emission and thermoluminescence dosimeters.

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
