Study on Luminescence Properties and Energy Transfer of SrCaSiO_4∶Eu~(2+),Ce~(3+) Phosphor

SrCaSiO4:Eu2+,Ce3+ has been prepared through high-temperature solid state reaction,and the spectrum and lifetime decay curves has been tested.The phosphors can match UV LED,and emit a broad band with a maximum at 500 nm.In SrCaSiO4:Ce3+,Eu2+ phosphors,energy transfer could been found between Ce3+ and Eu2+.In the fluorescent powder SrCaSiO4:Eu2+,the doping Ce3+ will make Eu2+ decay lifetime increase,and make Ce3+ decay lifetime become short,it also proves that there exist energy transfer.
