Aging effect on bonding properties of fluorescent neodymium materials

摘要

The neodymium complexes with nitrogen and oxygen donor pyrazoline ligands were synthesized by the conventional method. To observe the effect of the change in environment, the mixed ligand complexes along with pure neodymium-pyrazoline complexes were synthesized. Shelf-life of these newly synthesized materials was studied by the absorbance spectral peaks, whereby the aging effect was clearly seen in all these neodymium complexes. Considering the effect of time and shelf-life, the neodymium-pyrazoline complexes show comparatively lower stability than the mixed ligand complexes of neodymium. The detailed characteristics of these newly synthesized materials are presented in this manuscript.
