It is the "mobile phase" for the chromatography and may also be referred to as the eluent, eluting solvent, or solvent system.

In RP-TLC, the solvent systems are commonly mixtures based on water, methanol, acetonitrile, or aqueous buffers. The employed solvents and solvent blends ...

Make the solvent system more polar if you want a larger Rf or make it less polar if you want to decrease the Rf.
