The phosphors SrS : Eu and CaS: Eu doped with Mn were prepared by sulfurization flux method ( SFM ).
采用硫化助熔剂法制备了 SrS:Eu,Mn和 CaS:Eu, Mn 荧光粉.
The luminescence of Eu 3 + is also observed in TL emission spectrum of CaSO 4: Eu .
同时在CaSO4:Eu的热释 光发光 谱中还观察到了Eu3+的发光.
In addition , From emission spectrum, the as - prepared ultra fine luminescent LaPO _ 4∶ Eu powder can emit bright red luminescence.
Last year our EU and AM International labels won a SEMA award in the packaging area.
The effects of different doping concentration of Eu 2 + on the properties of Sr 2 Al 6 O 11 - based phosphor were studied.
