Study on the Preparation of MEH-PPV Langmuir-Blodgett Film

MEH-PPV 공액성 고분자 Langmuir-Blodgett막의 제작에 관한 연구

  • Published : 1997.11.30

Abstract

In this study, MEH-PPV was synthesized and MEH-PPV and its mixtures with PMMA were deposited on substrates with Langmuir-Blodgett(LB) technique and their photoluminescent char acteristics were investigated using UV-Vis absorption spectroscopy, and photoluminescence(PL) measurements. The surface morphology of the LB films of MEH-PPV and its mixture with PMMA were investigated using Atomic Force Microscopy(AFM). Electroluminescent devices using LB films were fabricated with Al and ITO as a top and bottom electrode, respectively, and their I-V characteristics were investigated.
