Abstract
Wet chemical synthesis of LiAEAlF6:Eu (AE=Mg, Ca, Sr or Ba) phosphors is described. Formation of single-phase compounds LiCaAlF6 and LiSrAlF6 was confirmed by XRD. LiCaAlF6:Eu and LiSrAlF6:Eu phosphors exhibited broadband emission corresponding to intraconfigurational transition 4f65d1→4f7(8S7/2). LiMgAlF6:Eu exhibits a narrow line emission corresponding to 6PJ→8S7/2 transition of 4f7 configuration besides the band emission. LiBaAlF6:Eu, on the other hand, was found to yield predominantly line emission.
