Recently, flux-materials have attracted considerable attention for improving the photoluminescence (PL) properties of luminescent materials. Herein, the phase structure, morphology, PL property, thermal stability, and cathodoluminescence (CL) property of Ba2La0.9Eu0.1SbO6 phosphors with and without the flux-materials of NH4F, C6H8O7, and H3BO3 were investigated and compared. At first, these mentioned flux-materials would barely affect the crystal structure through analyzing the X-ray diffraction patterns and Rietveld refinements. However, the morphology, PL intensity, thermal stability, lifetime, and CL performance were implicated by adding the flux-materials. Especially, the C6H8O7 flux-material could obviously improve the emission intensity and CL property of Ba2La0.9Eu0.1SbO6 phosphors with respect to the other samples. In addition, these flux-materials could enhance thermal stability and lifetime. In terms of quantum yield, the H3BO3 flux-material has the best optimization capabilities. Briefly, this work would provide a deep insight into a kind of suitable flux-materials to optimize luminescent materials in the synthesized processes.
