Abstract

The generation of white luminescence from polymer thin films, which contain excited-state intramolecular proton-transfer (ESIPT) dyes, was analyzed. This approach can be validated by mixing two different ESIPT dyes SOX and DOX with bluish-green (SOX) and orange (DOX) keto emissions in a polymer matrix. It is found that this binary mixture of ESIPT dyes emits broad luminescence in the visible region that is close to a whitish color with Commission Internationale de L'Eclairage (CIE) coordinates. The results show that due to the limited energy transfer, emissions from orange and bluish-green ESIPT dyes could be combined to generate white-light electroluminescence with a maximum luminance of 3100 cd m^-2.
