Strong green up-conversion emission was observed for the first time in europium and dysprosium co-doped strontium aluminate (SrAl 2O 4:Eu 2+,Dy 3+) phosphor under 980 nm infrared excitation at room temperature.

• 铕镝共掺的铝酸锶是一种新型的绿色长余辉荧光材料 ,经可见 -紫外光激发后 ,能发出超长时间的余辉。 本文首次用 980nm的红外激发光源激发SrAl2 O4 :Eu2 + ,Dy3+ 磷光体后 ,在室温下观测到了SrAl2 O4 :Eu2 + ,Dy3+ 的绿色上转换荧光。
