Abstract

Photoluminescence and stimulated emission measurements on poly(2,5-bis(2′-ethylhexyloxy)-1,4-phenylenevinylene) show only a slight thermal-dependence on the threshold for spectral line narrowing. Done between 15 and 300 K, the measurements showed a decrease in threshold intensity at lower temperatures, which can be mainly attributed to an increase in quantum efficiency. This deviation from the expected behavior for a four-level system is assigned to the dominant inhomogeneous broadening.
