中文摘要	zinc(ii)-2-(2-hydroxyphenyl)benzothiazolate complex is an excellent white-light-emitting material. despite some studies devoted to this complex, no information on the real origin of the unusually broad electroluminescent (el) emission is available. therefore, we investigate photoluminescent and el properties of the zinc complex. orange phosphorescent emission at 580 nm was observed for the complex in thin film at 77 k, whereas only fluorescent emission was obtained at room temperature. molecular orbitals, excitation energy, and emission energy of the complex were investigated using quantum chemical calculations. we fabricated the device with a structure of ito/f16cupc(5.5 nm)/zn-complex/al, where f16cupc is hexadecafluoro copper phthalocyanine. the el spectra varied strongly with the thickness of the emissive layer. we observed a significant change in the emission spectra with the viewing angles. optical interference effects and light emission originating both from fluorescence and from phosphorescence can explain all of the observed phenomena, resulting in the broad light emission for the devices based on the zn complex. we calculated the charge transfer integral and the reorganization energy to explain why the zn complex is a better electron transporter than a hole transporter.
