The EL device structure was [ITO/copper phthalocyanine (Cu-Pc) (15.0 nm)/N,N -di(α- naphthyl)-N,N -diphenyl-(1,1 -biphenyl)-4, 4 -diamine (NPB) (60.0 nm)/tris(8-hydroxyquinolinato)aluminum (Alq3): RuTPPCO (50.0 nm)/LiF (1.0 nm)/Al (200.0 nm)]. The co- deposited films of Alq3:RuTPPCO were utilized as the emit- ting layer to construct EL devices. Experimental results showed that energy transfer from Alq3 to RuTPPCO oc- curred in the codeposited films. The EL property of the co- deposited Alq3:RuTPPCO films with different RuTPPCO concentrations was described. For the EL device with the RuTPPCO concentration of 15% by weight, deep red elec- troluminescence at 656 nm with the maximum EL efficiency of 0.32 cd/A was achieved.展开更多

TPN was used as a ligand to link RuPc since it can not only modify the silver substrate but also deliver the nitrile groups protruding from the silver surface. Therefore,we can explore the relationship between the structure and the orientation of RuPc and the TPN\|modified substrate. The UV\|Vis spectra indicate a strong interaction between RuPc and TPN in the composite film. The result is further confirmed by the SERS spectra of RuPc\|TPN SAM,in which the vibrational bands arising from both the RuPc and TPN moieties appear clearly,indicating that the RuPc is successfully assembled on the TPN film.展开更多
