Luminescence of Eu(fod)(3) in a homologic series of simple alcohols

We present measurements on the luminescence of Eu(fod)(3) dissolved in a se ries of (deuterated) alcohols and mixtures hereof, to test local-field corr ections on spontaneous emission. The alcohols used are CH3(CH2)(m)OH, with m ranging from 0 for methanol to 9 for 1-decanol. Accordingly, the refracti ve index varies from 1.33 to 1.44. To test the influence of the intrinsic m olecular vibrations of the alcohols on the luminescence properties, also de uterated alcohols are used: CH3(CH2)(m)OD, with m = 0,1,3. Although the che mically homologic series of alcohols was carefully selected, small variatio ns in the local environment of Eu(fod)(3) complex upon changing the host (a lcohol), blur most of the local-field effect on spontaneous emission.
