Mn(2+) doped and Ce(3+)-Mn(2+) co-doped α-Sr(2)P(2)O(7) phosphors were prepared by a traditional high-temperature solid-state reaction route. The UV-vis excitation and emission spectra for all samples were investigated. Luminescence of Mn(2+) is assigned to from two different sites, which is similar to that of Ce(3+). Energy transfer from Ce(3+) to Mn(2+) in co-doped phosphors α-Sr(2)P(2)O(7): 0.03Ce(3+), xMn(2+) and α-Sr(2)P(2)O(7): xCe(3+), 0.1Mn(2+) was investigated by the excitation and emission spectra as well as the luminescence decays. Both Ce(3+)(1) and Ce(3+)(2) can transfer energy to two types of Mn(2+) ions.
通过传统高温固态反应路线制备了Mn(2+)掺杂和Ce(3+)-Mn(2+)共掺杂的α-Sr(2)P(2)O(7)荧光粉。研究了所有样品的紫外-可见激发和发射光谱。Mn(2+)的发光归因于两个不同的位点，这与Ce(3+)的情况类似。通过激发和发射光谱以及发光衰减研究了共掺杂荧光粉α-Sr(2)P(2)O(7): 0.03Ce(3+), xMn(2+)和α-Sr(2)P(2)O(7): xCe(3+), 0.1Mn(2+)中从Ce(3+)到Mn(2+)的能量转移。Ce(3+)(1)和Ce(3+)(2)都可以将能量转移到两种类型的Mn(2+)离子上。
