✦ Synopsis


We have observed a novel kind of luminescence due to direct bombardment by electrons accelerated in a semiconducting thin film adjacent to the phosphor layer. We call this emission solid-state cathodoluminescence because the physical process is similar to cathodoluminescence except that the electrons are accelerated in a solid instead of in vacuum. This phenomenon is also not ordinary electroluminescence. It can be observed not only in semiconductors but also in insulators. In this paper we introduce two different kinds of proof of this phenomenon.
