I suspect that you only want to simulate perfectly polished surfaces. If this is so, you don't have to specify anything about the 'surface'! All you need to do is provide the index of refraction of the materials touching; i.e. the scintillator, the air, and the silicon oil. In this case, the G4OpBoundaryProcess defaults to the 'glisur' model for dielectric_dielectric interfaces which are assumed to be perfectly polished finishes. You do NOT need to use the UNIFIED surface model!
Please, follow the following links for more information and specifically about the 'Unified Model' which only needs your above list of extra parameters.
Best regards, Peter
