Abstract
A liquid solution on the basis of dissolving a novel tetranuclear neodymium complex Nd4(TTA)10O12H22 (HTTA: 2-thenoyltrifluoroacetone) in polytrifluorochloroethylene oil was presented. The molecular structure of the complex was characterized by single-crystal X-ray diffraction. The optical properties of the liquid medium were studied. Enhanced emission was observed at 1064 nm when excited at 340 nm due to efficient energy transfer from TTA to the Nd3+ ions and the mechanism for energy transfer process was discussed in detail. The obtained fluorescent lifetime was 1.7 μs and the quantum yield value was 0.63%, which compare well with some other organic liquid media reported previously. Besides, this liquid shows outstanding properties with no toxicity and causticity, nonvolatility and high stability.
