Eu3+ or Sm3+ ions individually doped bismuth oxybromide (BiOBr) phosphors with three-dimensional flower-like microsphere morphology were prepared by a solvothermal method. The variation of ethylene glycol and ethanol concentrations affected the surface morphology of microparticles, which was investigated by field-emission scanning electron microscope images. The crystallinity and phase formation of...
A series of Eu2+ions doped BaZrSi3O9 phosphors were synthesized by a solvothermal reaction method. The X-ray diffraction patterns of BaZrSi3O9:Eu2+phosphors confirmed their hexagonal structure after the samples were sintered above 1300°C. The photoluminescence properties of BaZrSi3O9:Eu2+ phosphors were explored by measuring the excitation and emission spectra, and decay curves. The excitation spectra...
