Abstract
A DNA-lipid complex, where cationic surfactants are bonded to DNA, was synthesized and its optical property was examined by doping rare-earth chelates. The DNA lipid complex films to which several kinds of rare-earth chelates were doped were prepared, and their fluorescence quantum yields were examined. A 2 to 10-fold increase in quantum yield was observed as compared with conventional PMMA similarly doped. The improvement of the fluorescence quantum yield indicates that the use of DNA is promising in the development of new optical functional materials.
