Hydrothermal Synthesis and Upconversion Properties of Yb3+, Tm3+ Co-Doped Gd6MoO12 Phosphor with Regular Morphologies

Yb3+, Tm3+ co-doped Gd6MoO12 phosphors were prepared by the hydrothermal method. After tuning the PH value and EDTA, phosphors present different morphologies including hexagonal prisms, spindles, and spheres. Under 980nm excitation, the upconversion luminescence properties of the as-prepared phospho...

Zusammenfassung:Yb3+, Tm3+ co-doped Gd6MoO12 phosphors were prepared by the hydrothermal method. After tuning the PH value and EDTA, phosphors present different morphologies including hexagonal prisms, spindles, and spheres. Under 980nm excitation, the upconversion luminescence properties of the as-prepared phosphors are studied based on changing the synthesis condition. It is found that usage of EDTA and pH changing both play crucial key in the formation of morphology. Pumping power on the UC luminescence properties and level diagram mechanism of Gd6MoO12:Yb3+/Tm3+phosphor have also been discussed.
