Abstract :An isonicotinic acid N-oxide Zninsert ignore into journalissuearticles values(II); compound was characterized on the basis of elemental analysis. FTIR spectra of the compound and free isonicotinic acid N-oxide insert ignore into journalissuearticles values(INO); were recorded in the range 4000--400 cm-1. Cathodoluminescence insert ignore into journalissuearticles values(CL); spectra from the Zninsert ignore into journalissuearticles values(INO);2 complex were recorded. The luminescence data were interpreted in terms of the emission band at 470 nm. The green luminescence insert ignore into journalissuearticles values(\sim 470 nm); arises from Zn2+ transition 4T1 insert ignore into journalissuearticles values(4G); \to 6A1 insert ignore into journalissuearticles values(6S);. It shows a weak vibronic structure, and short lifetimes less than 150 m s. The lifetime and intensity of the signal are temperature dependent, and the parameters are reported for the 470 nm emission line.
