Bright yellow-emitting long persistent luminescence from Mn2+-activated strontium aluminate phosphor
文献摘要：
We developed bright yellow-emitting long persistent luminescence(LPL)materials Sr4Al14O25∶Mn2+and Sr4Al14O25∶Mn2+,N(N=Zr4+,Ho3+,Er3+)by high temperature solid-state reaction.The addition of Zr4+,Ho3+and Er3+can regulate trap distributions and improve energy storage ability of the materials.The LPL performance of SAO∶Mn2+,Ho3+is optimal,considering LPL intensity and duration time.Bright LPL of SAO∶Mn2+,Ho3+can be observed for 3 h by naked eyes in dark after removing the excitation source.Profiles of LPL spectra are different from those of PL,because the two types of Mn2+centers do not play equal parts in LPL and photoluminescence(PL).Trap depths of TL peaks centered at 354 K(peak 1)and 455 K(peak 2)are 0.60 and 0.72 eV,respectively.And peak 1 at 354 K is the effective TL peak responsible for LPL In SAO∶Mn2+,Ho3+,Mn2+ions doped in Al3+sites serve as emitting centers,and positively charged HoSr defects are the main effective trap centers.Finally,a feasible LPL mechanism of SAO∶Mn2+,Ho3+was proposed to clarify the generation process of LPL.
