phosphors were prepared by the high temperature solid-phase method

and their luminescent properties and the energy transfer process were investigated. Sr

614

624 nm emission lines under near-ultraviolet light (300~400 nm) excitation. The lifetime of Tb

decreased with the increasing addition of Eu

which proved there exist energy transfer process from Tb

to Eu

. When the mole fraction of Eu

was 0.07

the lifetime of Tb

dropped to 1.20 ms and the energy transfer efficiency was calculated to be 20.53%. Meanwhile

the energy transfer process from Tb

to Eu

was further studied by analyzing energy level structures of Tb

and Eu

. The phosphors exhibit good red luminescence properties

which can be used in white light emitting diodes (LEDs).
