Abstract

Influence of precursor intermediates (PI) on the synthesis of high efficient green emitting β-Ca₂SiO₄:Eu²⁺ (β-C₂S:Eu) phosphors were demonstrated by a novel liquid-phase-precursor (LPP) method utilizing (a) CaCl₂-EuCl ₃, (b) Ca(NO₃)₂-EuCl₃, (c) CaCl ₂-Eu(NO₃)_3, and (d) Ca(NO₃) ₂-Eu(NO₃)₃ combinations as precursors. The crystallinity and morphology of the PI analyzed using X-ray diffraction and high-resolution transmission electron microscopy measurements showed both the amorphous and crystalline type precursor intermediates (API and CPI) depending upon the metal-source materials. The final morphology and luminescence properties of β-C₂S:Eu phosphors were found to be strongly influenced by the crystallinity (amorphous and crystalline) and morphology of the PIs. The APIs have led to regular-shaped homogeneous phosphor particles with higher luminescence when compared with the CPIs.
