Abstract
We demonstrate for the first time that a large-area light emitting diode (LED) which generates ultraviolet (UV) light can be realized by organic-inorganic hybrid semiconductor; polysilanes (PSs). The LED based on the thin film of PS prepared by spin casting emitted 3.35 eV (370 nm) light. The emission efficiency was 0.05% at 77K and 0.01% at 190 K. Obtained results show that organic-inorganic hybrid semiconductor; PS can achieve novel properties as active material in LED device which cannot be done with pure organic or inorganic ones.
