title: [Spectroscopic properties of salicylaldehyde anil zinc and its thin film].
abstract: A new light emitting material, salicylaldehyde anil zinc (SAZ), was synthesized. It can form high quality nano-scale amorphous thin films on clean glass substrates by vacuum evaporation. Its structure, crystallization, thermal stability, and optical property were investigated by IR spectra, DTA-TG analysis, XRD spectra, UV-Vis spectra, and fluorescence spectra. Its energy band structure was confirmed by cyclic voltammogram and optical absorption band edge. Results show that the SAZ film is a thermally stable material, and can emit intense green fluorescence with a peak wavelength at 508 nm and a full width at half-maximum of 90.2 nm under UV irradiation. Its HOMO energy level is about -5.659 eV, LUMO energy level is about -3.054 eV, optical gap band is about 2.604 eV. The fluorescence decay of stored films under ambient atmosphere is more rapid than that of 8-hydroxyquinoline aluminum films. However, the fluorescence decay of the films under UV irradiation is slower than that of 8-hydroxyquinoline aluminum films.
