Synthesis of Red-Emitting AgGd0.9Eu0.1(MoO4)2 Phosphors by Precipitation at Room Temperature

A series of Eu3+‐doped AgGd(MoO4)2 red phosphors with well‐defined shape and size were prepared via a precipitation method at room temperature. The samples were characterized by X‐ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and photolumin...

Description
Summary:A series of Eu3+‐doped AgGd(MoO4)2 red phosphors with well‐defined shape and size were prepared via a precipitation method at room temperature. The samples were characterized by X‐ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and photoluminescence (PL) spectroscopy. The crystallinity, particle size, morphology, and luminescent properties of the as‐prepared products were tuned by controlling the reaction conditions such as the precipitation reagents used and the pH of the initial solution. XRD results showed that all of the synthesized samples adopted a pure tetragonal structure. The formation mechanism of AgGdMo2O8 was investigated in detail, and two intermediates were found to be essential. Photoluminescence properties of the as‐prepared AgGd0.9Eu0.1(MoO4)2 phosphors under diverse experimental conditions were also studied systematically, and their emission spectra showed emission characteristic of Eu3+.
