Abstract：In this paper, the new emitting material zirconium complex with 8-hydroxyquinoline and phenol (Zr(OPh)2q2), which can form high quality nano-scale amorphous thin films at glass substrates cleaned by vacuum evaporation, was synthesized. Its crystallization，thermal stability，the structure of energy band and PL mechanism were investigated respectively by FTIR spectra, DTA-TG analysis , SEM, XRD spectra, UV-Vis absorption spectra and fluorescence spectra. Results show that the Zr(OPh)2q2 is a thermally stable material, whose melting point is 381.2 ℃, decomposition temperature is 467.1 ℃, whose film can emits intense yellow-green fluorescence with peak wavelength at 525 nm and a full width at half-maximum of 107.6 nm under UV excitation(390 nm), powder has intense yellow fluorescence, therefore it may be a excellent electroluminescent material.
