Spectroscopic and Luminescence Properties of an Isonicotinic Acid

摘要

An isonicotinic acid N-oxide Zn(II) compound was characterized on the basis of elemental analysis.FTIR spectra of the compound and free isonicotinic acid N-oxide (INO) were recorded in the range 4000-400 cm~(-1).Cathodoluminescence (CL) spectra from the Zn(INO)_2 complex were recorded.The luminescence data were interpreted in terms of the emission band at 470 nm.The green luminescence (approx 470 nm) arises from Zn~(2+) transition ~4T_1(~4G) -> ~6A_1 (~6S).It shows a weak vibronic structure,and short lifetimes less than 150 mu s.The lifetime and intensity of the signal are temperature dependent,and the parameters are reported for the 470 nm emission line.
