Abstract
A series of lanthanide tetrakis-trifluoroacetates {(detaH2)2[La2(tfa)8]2(CH3CN)5(H2O)2}n and (detaH2)n[Ln(tfa)4]2n (Ln = Pr–Eu), mixed-ligand complexes [La(tfa)3(CH3CN)(H2O)]n, [Gd(tfa)3(deta)2](iPrOH) and [Yb(tfa)2(deta)2](tfa), as well as detaH2(tfa)2 were isolated and characterized. All lanthanide tetrakis-trifluoroacetates contain two types of 1D anionic chains [Ln(tfa)4]nn− and cavities occupied by detaH22+ cations and solvating H2O and CH3CN molecules. The thermal behavior of (detaH2)n[Ln(tfa)4]2n in air is investigated by TGA, in situ VT-PXRD and total X-ray scattering with PDF analysis, and the formation of metal fluorides occurs upon heating to 300 °C. The application of solution with lanthanide trifluoroacetates and diethylenetriamine (deta) as precursors for chemical deposition of β-NaGdF4:Er,Yb,Nd thin films is reported. The deposited β-NaGdF4:Er,Yb,Nd thin film demonstrates up-conversion luminescence under 980 and 808 nm laser excitation.
