Figure 5From: Growth and characterization of thin Cu-phthalocyanine films on MgO(001) layer for organic light-emitting diodesCurrent density-voltage and luminance-voltage characteristics for TOLED devices with different anodes. Al (blue, S1), Fe(100)/MgO(100) (green, S2), Fe(100) (red, S3), and poly-Fe (black, S4) anodes. More detailed information about each sample structure is given in Table 1.Back to article page
