    摘要: The invention describes a light-emitting device which comprises at least a substrate (1), an anode (2), a first hole transport layer (3), a light-emitting layer (5) and a cathode (6), and in which a first hole blocking layer (4) is arranged between the first hole transport layer (3) and the light-emitting layer (5). The hole blocking layer (4) reduces the concentration of holes which reach the light-emitting layer (5) and thus the concentration of holes, which are usually the majority charge carriers, can be adapted to the electron current.

A layer, which has a high reflection in the wavelength range of the plasma emission (145 to 200 nm) and a high transmission in the visible wavelength range, is provided on the front plate. The front plate includes a glass plate on which a dielectric layer, a protective layer, a reflective layer are provided. The reflective layer reflects UV light emitted in the direction of the front plate back towards phosphors. The optical properties of the UV light reflecting layer are realized with inorganic particles with a particle diameter of between 200 nm and 500 nm and a layer thickness from 0.5 &mgr;m to 5 &mgr;m, or with agglomerates of inorganic particles with a particle diameter of between 10 nm and 200 nm and a layer thickness of 0.2 &mgr;m to 10 &mgr;m.
