[Preparation and characterization of 2(8-hydroxyquinoline)-2( phenol) zirconium thin film].
In this paper, the new emitting material zirconium complex with 8-hydroxyquinoline and phenol (Zr(OPh)2 q2), 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)2 q2 is a thermally stable material, whose melting point is 381.2 degrees C, decomposition temperature is 467.1 degrees C, 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.
