Experiments to observe anthracene radiation excited by hot electrons emitted from PZT ferroelectric substances by polarization inversion were performed with using 2.5 and 1.0 mm thick PZT disk type samples. The PZT electron source was fabricated with sandwiching a comb and a flat type electrode formed on the both sides of PZT plate. Then about 1nm thick semi-conductive C-S-Au film was equipped on the comb type electrode side of PZT element. The anthracene layer was over coated on the C-S-Au film on the comb type electrode. When the polarization was inversed by an impulse voltage application, some radiation was observed on the comb type electrode side. It was difficult to distinguish the anthracene radiation from the surface discharge. In order to distinguish the anthracene radiation, additional experiments must be performing by optimizing the semi-conductive properties of C-S-Au film depending on the atomic composition and the thickness, the comb type electrode structure and the impulse voltage shape for the polarization inversion.
