| Research Abstract |
Responses of luminescent and fluorescent materials under an applied electric field have been examined to investigate their applicability for inspection of ceramic materials developed for fusion blanket systems. An inorganic electro-luminescence (EL) material has been applied to sintered SiC plates with the electrical conductivities of ~1x10^<-6>S/m and ~1x10^<-2>S/m. The deference in the conductivities could be detected by a luminescence of the material. The organic materials of DiBAC4(3) and GFP showed a change in their fluorescent region according to the electric field. The DiBAC4(3) liquid has been applied to a metal plate coated with an Er2O3 ceramic insulating layer. The intensity of the fluorescent of DiBAC4(3) decreased at an uncoated area on the plate. It is considered that the distribution of DiBAC4(3) has been changed according to the electrical potential or current distribution on the plate and could detect the uncoated area.
