Anong the present three types of electric field-induced luminescence we noticed similarities between the inorganicand organic materials in electric field intensity. In this high electric field range SiO_2 has three functons: acceleration,excitation and multiplication of electrons. Based on the acceleration effect, cathodoluminescence-like emission of organicmolecules and polymers was found. By using the three functions of SiO_2 or II-VI compounds and the heterojunction ofinorganic and organic material we realized different variants of mixed excitation in electroluminescence.
