Fluorescence Measurement ofOrganicElectroluminescent Material

Introduction

Screens, lighting, and other products that incorporate organic electroluminescent (EL) materials are being developed on a daily basis in the electrical and electronic goods sector. Organic EL material development involves the synthesis of new substances and verification of their optical properties using photoluminescence (PL) technique. Researching the PL allows us to find materials that emit light with high efficiency, and we can elucidate the mechanism of its fluorescence in solution. Organic EL materials are developed through this process to meet specific criteria that can include hue, low energy consumption, or high luminous efficiency. In order to evaluate organic EL materials, fluorescence must be measured quickly and accurately over a wide range of wavelengths. Introduced here are the measurements of porphyrin solution (solvent: chloroform), an organic EL material, using an RF-6000 spectrofluorophotometer, with the help of the Institute for Basic Science, Pohang University of Science and Technology (POSTECH), South Korea.
