| Abstract(in English) | The spectral imaging for electroluminescence (EL) characterization in the light emitting diode based on polymer blends was performed using the imaging microspectroscopy system, which has functions both microspectroscopy measurement and imaging analysis. EL spectra of whole units (the observed area was composed of ensemble of 1.25×1.04μm unit) were classified into several spectra according to the difference of spectral properties, such as the emission peak wavelength and the spectral linewidth. These classified spectra were stored in a spectral library and arbitrary colors were assigned to them. Using this imaging technique, it is possible to elucidate what and where emission species are located within an emission surface. We observed the irregular spatial distribution of areas with different EL spectra and, furthermore, found that EL spectral images change with increasing applied voltage. These observations may be attributable to the transfer of emission site in the blend polymer LED. |
