Solvent-vapour treatment induced performance enhancement of amplified spontaneous emission based on poly[2-methoxy-5-(2’-ethyl-hexyloxy)-1,4-phenylene vinylene]

【摘要】 In this work,performance enhancements of amplified spontaneous emission(ASE) from poly[2-methoxy-5-(2éthyl-hexyloxy)-1,4-phenylene vinylene](MEH-PPV) have been achieved via solvent vapour treatment.Correlations between the morphology of the film and the optical performance of polymer-based ASE are investigated.The active layers are characterised by atomic force microscopy and optical absorption.The results show that the solvent-vapour treatment can induce the MEH-PPV self-organisation into an ordered structure with a smooth surface,leading to enhanced optical gain.Thus the solvent-vapour treatment is a good method for improving the optical properties of the MEH-PPV.更多还原
