Abstract
This paper discusses the material factors which have led to a recent breakthrough in polysilane light-emitting diodes (LEDs) made from a diaryl polysilane, poly[bis(p-n-butylphenyl)silane] (PBPS), by comparing them with LEDswhich employ a conventional polysilane, poly(methylphenylsilane). In contrast to LEDs based on conventional polysilanes in which a weak ultraviolet Electroluminescence (EL) plas detected either with a strong broad visible ELor only at low temperatures, room-temperature pure near-ultraviolet EL wasobserved with a quantum? effciency of 0.1% photons/electron with an electron injecting Al electrode in PBPS-LEDs. We examined the spectroscopic, electronic and structural properties of PBPS, and ascribed to them the improvements observed in the EL characteristics. We also mention the possible future direction of polysilane LED research and other potential optoelectronics applications of polysilanes to the active medium of lasers.
