Abstract

The synthesis of neodymium carboxylates (neodecanoate and 3,5,5-trimethylhexanoate) and theiruse for the development of Nd-loading liquid organic scintillators is considered. Neodymiumcarboxylates were obtained by one-step (3,5,5-trimethylhexanoate) and two-step synthesis(neodecanoate). The composition of the obtained compounds was confirmed by IR spectroscopy,elemental analysis and MALDI-TOF MS. To introduce neodymium carboxylates into a liquidorganic scintillator, it is proposed to use an additional solvent, tributylphosphate. It has been shownthat the light output of the scintillator when used is higher than without it, and is more than 60% up to a neodymium concentration of 12 g/l.
