When the K2Sr(MoO4)2 system is doped with Eu3+ ions, energy transfer occurs from MoO4 groups to Eu3+ ions. The results show that all samples can be efficiently excited by UV (393 nm) light. A narrow emission spectra obtained shows intense red emission peaking at 617 nm. The characteristic emission spectrum is due to the D07 F2 transition of Eu3+. The red-emitting K2Sr(MoO4)2:Eu phosphor may be potential candidate in the fabrication of white light emitting diodes (LEDs). |
