On the dependence of the luminescence intensity of rare-earth compounds with pressure: a theoretical study of Eu(TTF)(3)2H(2)O in polymeric solution and crystalline phases
Ol. Malta et al., On the dependence of the luminescence intensity of rare-earth compounds with pressure: a theoretical study of Eu(TTF)(3)2H(2)O in polymeric solution and crystalline phases, CHEM P LETT, 307(5-6), 1999, pp. 518-526
Theoretical models for ligand-rare-earth-ion energy-transfer processes and
numerical solutions of the rate equations are used to analyse the dependenc
e of the 4f-4f emission intensity and the D-5(0) excited state lifetime wit
h an applied external pressure, in Eu3+ complexes. Pathways for the intramo
lecular energy-transfer process between the ligands and the rare-earth ion
are proposed. The theoretical results agree well with the experimental data
for the Eu(TTF)(3)2H(2)O compound in a polymeric solution and crystalline
form. (C) 1999 Elsevier Science B.V. All rights reserved.
