چکیده انگلیسی
The J-aggregate thin film of an oxacyanine dye has been prepared by the spin-coating method on a quartz plate and its photophysical property has been studied. Coherent size of the J-aggregate was estimated to be ca. 4–7 by means of the fluorescence radiative lifetime. Photostability of the J-aggregate thin film and J-aggregate/poly(dimethylsilane) composite thin film has also been examined. Poly(dimethylsilane) vacuum deposited on the J-aggregate thin film was found to markedly enhance the photostability. This stabilization mechanism has been discussed in terms of the electron transfer from poly(dimethylsilane).
