An ion-implantation system designed and fabricated indigenously is des
cribed. It consists of a versatile ion source, Einzel lens system, EXH
velocity filter, dose measuring equipment, and target chamber. The io
n-implantation system fabricated has been used to prepare ion-implante
d luminescent phosphors by implanting Sb+ ions into CaS. (C) 1995 Amer
