TDE is excellent with fluorescence - it also acts as an antifade.  You
can get exactly the RI you want by adjusting the amount of water in it.
I've used it for the highest resolution micrographs I ever took.  The 
one problem is that there are some security restrictions on supplying
it since it is a precursor for mustard gas.  But that just means you
may have to sign some forms.  Do check out the reference Stanislav 
sent because it really does seem like the solution to your problem.

From your previous message, it seems likely that Vectashield is probably
not actually the RI you reported, if all is OK in oil.

Thank you for your advice!

The price seems to be cheap, but I wander how it works with fluorescence. At the moment probably I will stay with my vectashield so as to not chang to many things in one go.

I would also consider switching to a mounting medium with correct refractive index (=same RI as immersion oil)  2,2-thiodiethanol comes to mind.  See Staudt, 2007.  A 500 ml bottle can be had for ~$30.
