英文摘要	Energy-transfer processes from Ce(3+) to Eu(2+)/Mn(2+) and from Eu(2+) to Mn(2+) in host CaSiO(3) are studied. Co doping Ce(3+)/Mn(2+) or Eu(2+)/Mn(2+) is an effective approach to enhance the orange-reddish emission of Mn(2+). The ion-size compensation effect between Eu(2+) and Mn(2+) causes more Eu(2+) to be doped into the CaSiO(3) lattice, which benefits the increase of the energy transfer efficiency from Eu(2+) to Mn(2+). Additionally, the suitable spectrum overlapping of the Eu(2+) emission to the first excited state (4)T(1) of Mn(2+) as well as the formation of Eu(2+)/Mn(2+) clusters may be other causes of the enhanced Mn(2+) luminescence. Eu(2+)/Mn(2+) codoped samples can be very excited by near-UV. The excitation spectrum of Ce(3+) covers a different wavelength range from that of Eu(2+) (normally blue shift occurs); thus, replacement of Ce(3+) for Eu(2+) may make phosphors excited by shorter wavelengths. The results in this work may provide some clues for designing novel red phosphors for white-light UV light-emitting diode applications.
