Abstract

Lanthanium tungstates (where Ln = La or Gd) doped with dysprosium ion and incorporated into silica xerogel were prepared by the sol-gel process. X-ray diffraction (XRD) and transmission electron microscopy (TEM) methods were used to investigate structural and morphological properties of the obtained materials. Reflectance and emission spectra were measured at room temperature. These materials exhibit strong absorption band in the UV region. Moreover, photoluminescence spectra contain the characteristic emission bands of Dy ³⁺ in the host matrix. In particular, yellow emission at 575 nm (⁴F_9/2-⁶H_13/2) and blue emission at 484 nm (⁴F_9/2-⁶H_15/2) were observed due to the excitation energy transfer from WO42- group to Dy(III) ion upon excitation at λ_exc = 240 nm which is the important finding result of this paper. These results are supplemented by the analysis of the luminescence kinetics of Dy(III) ions in the studied materials.
