Synthesis and Luminescent Properties of M₂P₂O₇:Eu³⁺ (M = Ca, Sr, Ba ) Phosphors

Abstract:

A series of orange-red phosphors M₂P₂O₇: Eu³⁺ (M = Ca, Sr, Ba ) were prepared by traditional solid-state reaction method. X-ray diffraction analysis confirmed the formation of Ca₂P₂O₇, Sr₂P₂O₇ and Ba₂P₂O₇. Scanning electron-microscopy observation indicated a narrow size-distribution of about 0.6~1 μm for the particles with a quadrate shape. Photoluminescence spectra of M₂P₂O₇(M = Ca, Sr, Ba ): Eu³⁺ phosphors showed a strong excitation peak around 393 nm, and Ca₂P₂O₇: Eu³⁺, Sr₂P₂O₇: Eu³⁺ and Ba₂P₂O₇: Eu³⁺ phosphors showed strong emission bands peaking at about 593 nm, which suggests that the Eu3+ ion is occupy the site with center of symmetry.
