Site occupation and energy transfer in full color emitting phosphor Ba2Ca(BO3)2∶Ce3+(K+),Eu2,Mn2+
文献摘要：
White light-emitting diodes(WLEDs)fabricated by single-phase full color emitting phosphor are an emerging solution for health lighting.The crystallographic site occupation of activators in a proper host lattice is crucial for sophisticated design of such phosphor.Here,we report a high quality white light-emitting phosphor Ba2Ca(BO3)2∶Ce3+(K+),Eu2+,Mn2+with spectral distribution covering whole visible region.Blue light emission originates from Ce3+ions occupying preferentially Ba2+site by controlling synthesis conditions.Green and red lights are obtained from Eu2+occupying Ba2+(and Ca2+)site and Mn2+occupying Ca2+site,respectively.In this triple-doped phosphor,strong red emission with a low concentration of Mn2+is realized by the efficient energy transfer from Ce3+and Eu2+to Mn2+.Furthermore,high quality white light is accomplished by properly tuning the relative doping amount of Ce3+(K+)/Eu2+/Mn2+based on efficient simultaneous energy transfer.The results indicate that Ba2Ca(BO3)2∶Ce3+(K+),Eu2+,Mn2+is a promising white light-emitting phosphor in WLEDs application.
