Mathematical modeling of the colour characteristics of an electroluminescent layer with blue emission

Summary form only given. The electroluminophors-substances, emitting light in an electric field, are used in optical systems where equal surface brightness is needed- for example, in displays, indicators, etc. The mechanism of light emission-electron transition between the conductivity zone and a fixed energy level in the forbidden band in a microcrystal, restricts the possible emission colours. There is only a small number of electroluminophor types. Each type has its own fixed colour. In case of electroluminophors of pre-breakdown type (dust-like microcrystal particles), a wide diversity of colours can be reached by mixing electroluminophors of different types -with blue, green and red emission. These electroluminophors are used in the form of capacitors with about 50 micrometers thick dielectric layer in which they are bound by a transparent polymer. The light is emitted through the transparent electrode
