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.

β-NaYF4 microcrystals co-doped with Yb3+, Er3+/Tm3+, and Gd3+ ions were synthesized via a hydrothermal method using rare-earth chlorides as the precursors. The SEM and XRD data show that the doped β-NaYF4 form uniform hexagonal prisms with an approximate size of 600–800 nm. The partial substitution of Y by Gd results in size reduction of microcrystals. Upconversion luminescence spectra of microcrystals upon 980 nm excitation contain characteristic intra-configurational ff bands of Er3+/Tm3+ ions. An addition of Gd3+ ions leads to a significant enhancement of upconversion luminescence intensity with maxima at 5 mol % of dopant.
