Abstract
The phosphors Bi1-xPO4:xEu3+(x=0.01-0.08) were synthesized by the conventional solid-state reaction method. The crystal structure,morphology,photoluminescence properties and concentration quenching of these phosphors were systematically investigated. The powder X-ray diffraction revealed that the samples BiPO4:Eu3+transform from high-temperature monoclinic phase (HTMP) to low-temperature monoclinic phase (LTMP) with the increasing Eu3+content. All the samples show the characteristic red emission of Eu3+ions using the fluorescence spectrometer. The concentration quenching of Eu3+in BiPO4phosphor can be mainly attributed to multiple-multiple interaction.
