Abstract
Luminescence properties of YBO3-GdBO3 solid solutions doped with Tb3+ have
been investigated in order to understand the energy transfer processes betw
een Gd3+ and Tb3+ in these phosphors. The critical atomic fraction (X-c) an
d the critical distance (R-c) for efficient energy migration among Gd3+ ion
s were derived. In YBO3-GdBO3 : Tb solid solutions, (Gd3+-BO33-) absorbs ex
citation energy more efficiently than (Y3+-BO33-) in the VUV region. (C) 20
