摘要
采用固相反应制备了公式为RE(NbxTa1-x)O4 (RE = Y或Gd, x = 0-1)的未掺杂钇和钆钽铌酸盐样品。研究了其可见光和紫外光谱区的光学和发光特性。基体中铌含量为中间值的铌钽酸钇和重铌掺杂的铌钽酸钆的发光强度最大。
Luminescent and scintillation characteristics of RE(NbxTa1−x)O4 compounds (RE=Y or Gd)
Samples of undoped yttrium and gadolinium tantalo-niobates with common formulae RE(NbxTa1-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.
