Electroluminescent (EL) diodes utilizing metal-free phthalocyanine (H/sub 2/Pc) have been fabricated by the vacuum evaporation method. The EL characteristics of the diodes depending upon the metal cathode and the characteristics of the diodes with the coevaporated layer with 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM) have been investigated. We have demonstrated the infrared electroluminescence originated from the radiative transition corresponding to the Q band of H/sub 2/Pc by taking the energy band structure into consideration.
