• Stable d. c. electroluminescence is observed in a cell with M-I-S structures in the form of thin films(Ta-Ta_2O_5-ZnS:TbF_3-Au). To be able to observe d. c. electroluminescence in the cell, the Ta_2O_5 insulating layer must be about 1000Å-5000Å thick and treated by heating in air at 250℃ for about 10 minutes. Through such heat treatment, the d. c. conductance of the <Ta>_2O_5 layer increases remarkabley (about 10-3 times). The increase is due to the transition from an anomalous Poole-Frenkel effect to a normal one in the conduction process. This heat-treated <Ta>_2O_5 layer plays an important role in the creation of hot electrons required to excite the electroluminescent cell.
