Lanthanide-binding peptide tags (LBTs) containing a single cysteine residue can be attached to proteins via a disulfide bond, presenting a flexible means of tagging proteins site-specifically with a lanthanide ion. Here we show that cysteine residues placed in different positions of the LBT can be used to expose the protein to different orientations of the magnetic susceptibility anisotropy (de...

It has been an open question whether Nd3+ ions are incorporated into the crystalline phase in oxyfluoride glass ceramics or not. Moreover, relative research has indicated that spectra characters display minor differences between before and after heat treatment in oxyfluoride glass compared to similar Er3+-, Yb3+-, Tm3+-, Eu3+-, etc.-doped materials. Here, we have studied the distribution of Nd3...

Rare earth (Yb3+, Ho3+, Tm3+) yttrium disilicate phosphors were produced by sol-gel technique and heated at 1050 °C temperature. The sizes of the vary between 20-30 nm according to images obtained from Transmission Electron Microscope. up-conversion (UC) emissions nanopowders measured in range 500–900 wavelength under 950 laser excitation. A linear increase with power was observed emission inte...

We report the growth and optical characteristics of Tm,Yb-codoped ZnO (ZnO:Tm,Yb) films on nanowires (NWs). The conditions NWs are optimized by changing duration as well temperature VI/II ratio, which grown sapphire (0001) substrates. Photoluminescence (PL) characterization ZnO:Tm,Yb optimum is performed with excitation different lasers to investigate mechanism energy transfer between Tm3+ Yb3+...

Composite systems were prepared by doping NaYF4 (NYF) with lanthanide cations (Yb3+, Er3+, Tm3+), TiO2, and gold nanoparticles to exploit the light conversion properties of NYF its possible impact on photocatalytic activity composites. The composites synthesized via solvothermal crystallization obtained structures anatase hexagonal NYF, 5–7 nm. presence enhanced photoactivity TiO2 towards Rhoda...
