High pressure luminescence studies have been made on several tris rare earth betadiketonates. From this information the pathway for intramolecular energy transfer between ligand and rare earth ion localized levels is clearly established. The emission from europium dibenzoylmethide (EuDBM) and europium thenoyl-trifluoroacetylacetonate (EuTTF) is examined in depth. Further studies are presented on other Eu chelates as well as on samarium and terbium complexes. A brief discussion of the effects of pressure on processes internal to the rare earth ion or the ligand is also presented.
