Enhancement of luminescence properties of a KSrPO4:Eu2+ phosphor prepared using a solution method with a water-soluble phosphate oligomer

Abstract

A novel phosphate raw material having an oligomeric structure with desirable stability and solubility under aqueous conditions was prepared via an esterification reaction between H3PO4 and ethylene glycol under reflux. A blue emitting KSrPO4:Eu2+ phosphor with high luminescence was subsequently synthesized using a polymerizable complex (PC) method with the prepared phosphate oligomers as a source of P. KSrPO4:Eu2+ thus prepared exhibited higher emission intensity than samples prepared using a solid state reaction method or the PC method using H3PO4. This high luminescence was attributed to the excellent homogeneity of the constituents in the sample. It was found that KSrPO4 doped with more than 3 mol% of Eu2+ showed a new low-energy emission band at approximately 480 nm, in addition to the known emission band at 428 nm. This new feature was speculated to be derived from disordering of K and Sr ions caused by the high homogeneity of the constituents. Moreover, it was confirmed that thermal quenching of emission at 428 nm above 423 K was recovered in samples doped with more than 7% of Eu.
