In this work, luminescence spectroscopic and temporal dynamic properties of high energy elementary excitations in CdF₂-CaF₂ superlattices have been studied utilising excitation with vacuum ultraviolet and X-ray synchrotron radiation while comparing the results with those obtained for CdF₂ and CaF₂ bulk crystals. It is shown that the optical properties of the superlattice structures are determined by exciton emission in the CdF₂ monolayers. The experimental manifestations of exciton confinement phenomena are discussed.
