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.

在外加电场下的发光和荧光材料的响应已被检查，以调查其适用性检查的陶瓷材料开发的聚变包层系统。将无机电致发光材料应用于烧结SiC板，其电导率为~ 1 × 10 ~（10）<-6>S/m和~ 1 × 10 ~（10）<-2>S/m。电导率的差异可以通过材料的发光来检测。DiBAC 4（3）和GFP的有机材料显示出根据电场的荧光区域的变化。将DiBAC 4（3）液体施加到涂覆有Er 2 O3陶瓷绝缘层的金属板上。DiBAC 4（3）的荧光强度在板上的未涂覆区域处降低。认为DiBAC 4（3）的分布已根据板上的电势或电流分布而改变，并且可以检测未涂覆区域。
