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.

YPO4 nanowires (NWs) and nanoparticles (NPs) have been synthesized by hydrothermal methods respectively in the absence and presence of EDTA. The Eu3+ and Yb3+ codoped YPO4 NWs and NPs prepared directly from hydrothermal systems show efficient red down-conversion luminescence (DL) and upconversion luminescence (UL) at room temperature without further annealing process. EDTA plays a critical role in controlling the morphologies of YPO4 nanocrystals in hydrothermal systems and enhances both the DL and UL intensities of Eu3+ by the factor of 100%. Monodispersed Eu3+ and Yb3+ codoped YPO4 NPs will be a new candidate for application in infrared displays and biological labels.

We report the obtention ofβ-NaLuF4microcrystals doped with Er3+ions by the surfactant-assisted hydrothermal method. It was found that shape modulation could be realized by changing the surfactants (ethylenediaminetetraacetic acid, polyvinylpyrrolidone, and trisodium citrate) introduced into the reaction system. The surfactants can strongly control the size and shape of as-prepared samples through absorbing on the surface of primary particles and/or coordinating with rare earth ions. Hexagonal prism-likeβ-NaLuF4:Er3+microcrystals demonstrate intense upconverted luminescence (UCL) pumped by 1.54 μm infrared laser in comparison with hexagonal tube-like, disk-like, and sphere-like microcrystals, which exhibit great distinction. More interestingly, a synergistic effect combined dual mode (i.e., downconversion and upconversion) with 8% absolute enhancement rate of the red emission centered at 659 nm (4F9/2→4I15/2) is witnessed in hexagonal prismsβ-NaLuF4:Er3+phosphors by employing the dual wavelength 416 nm and 1.54 μm excitation source for the first time.
