Abstract(in English) The temperature dependence of the electrical characteristics of a SrS : Ce thin-film electroluminescent device is being investigated. The positive temperature dependence of the conduction charge is due to the positive temperature characteristics of the dynamic space charge. The dynamic space charge generation requires about 19 meV activation energy. From the significant trailing edge emission at low operating temperature, it is conclude, that Cerium ionization takes place even at low operating temperatures. At low operating temperatures a prethreshold current is observed at the leading edge. This pre-threshold current is attributed to charge stored at, and released from, shallow interface levels. At low temperature, the prethreshold current is concluded to be a mere continuation of leakage current.
