Abstract
The paper presents the investigation of the poly(3,3'-phthalidylidene- 4,4'-biphenylylene) (PPB) film electroluminescence (EL). EL was found to be of threshold origin, the threshold being 20 B. The voltage varie d within a range of 0 V to 100 V. The quantum efficiency was 10%. The results obtained led to a conclusion that EL is due to the recombinati on processes developing in the polymer proper, for light-emitting acco mpanying the sample failure belongs to a quite different spectrum area . EL arises when the polymer is in a dielectric state. There is no EL when the polymer is in a conducting state.
