Abstract: Abstract: The luminescence hosts K3YF6 and K3GdF6 were obtained in a single-crystal form. Their crystal structure was determined from single-crystal X-ray diffraction data. Both crystals adopt monoclinic system with space group P21/n, . Lattice parameters for K3YF6 are refined to the following values , , , and for K3GdF6 , , , . The vibrational analysis, IR and Raman spectroscopy at room temperature, was applied to these compounds in order to study the site symmetry of Y3+ and Gd3+ ions. [Copyright &y& Elsevier]
