A commercial Mn4+-doped phosphor with deep-red emission has attracted attention in recent years. This can provide red components in the fabrication of warm white light-emitting diodes (WLEDs). The Ba2YNbO6:Mn4+ phosphor is successfully synthesized through conventional solid-state reaction. The crystal structure, composition, and doping site were investigated using X-ray diffraction (XRD), Fourier...
A series of (4−x)MgO·xMgF 2 ·GeO 2 :0.02Mn 4+ deep-red nanosized phosphors with orthorhombic symmetry was synthesized via a sol–gel process using CF 3 COOH as fluorine source. The microstructure, composition, morphology, and grain size of the samples, and the effect of synthesis conditions were investigated by powder X-ray diffractometry, X-ray photoelectron spectroscopy,...
