Abstract

Samples of undoped yttrium and gadolinium tantalo-niobates with common formulae RE(Nb_xTa_1-x)O₄, where RE = Y or Gd, and x = 0-1, have been obtained by solid-state reaction. Optical and luminescent characteristics in visible and UV spectral regions have been studied. The most intense luminescence is determined for yttrium tantalo-niobates with intermediate value of Nb content in the matrix and for heavy Nb - doped gadolinium tantalo-niobates.
