摘要:
A thin film electroluminescent (EL) device comprises a transparent electrode (32), a first insulating layer (34), a luminescent layer (35) and a back electrode (37), said luminescent layer consisting of column polycrystals formed by independently evaporating luminescent host material and an activator (Im) and then combining evaporated substances on a substrate. Electrons (E) in the luminescent layer are accelerated by an electric field applied from outside, efficiently collide against the activator (Im) without being intercepted by interfaces between crystalline particles. A further insulating layer (33) is interposed between said transparent electrode and said first insulating layer, said further insulating layer having a refractive index intermediate of those of said transparent electrode and said first insulating layer. The thin film EL device can be used for display, illumination, writing, reading out and erasure of signals of photo-recording medium.
