On the dependence of the luminescence intensity of rare-earth compounds with pressure: a theoretical study of Eu(TTF)32H2O in polymeric solution and crystalline phases

摘要: Abstract Theoretical models for ligand–rare-earth-ion energy-transfer processes and numerical solutions of the rate equations are used to analyse dependence 4f–4f emission intensity 5 D 0 excited state lifetime with an applied external pressure, in Eu 3+ complexes. Pathways intramolecular process between ligands rare-earth ion proposed. The theoretical results agree well experimental data Eu(TTF) 3 2H 2 O compound a polymeric solution crystalline form.
