摘要：
The electroluminescence(EL) properties of a green phosphorescence dye, (dmbpy)Re(CO)(3)Cl, and a red fluorescence dye, DCM, co-doped polyvinylcarbazole(PVK) thin film were studied. The clear and pure red emission from DCM were observed from PL and EL spectra of (dmbpy)Re(CO)(3)Cl(>2.0 wt. %):DCM(> 0.5 wt. %)-doped PVK films. The optimized device ITO/ (dmbpy)Re(CO)(3)Cl (10 wt. %):DCM(1.0 wt. %):PVK/Al shows the highest EL efficiency of 0.42cd / A at current density of 10 mA/cm(2), which is more than ten times that of the DCM(1.0 wt. %): PVK devices.
