We developed flexible green phosphorescent organic light-emitting devices (OLEDs) on copy paper substrates. Poly-2-chloro-p-xylylene and poly-4-vinylphenol were used as buffer layer for reducing the surface roughness and protecting the absorption of water and organic solvents during photolithography process. Sputtered Al/Ni and evaporated Ca/Ag were used as anode and semitransparent cathode, respectively. The flexible OLED on the copy paper substrate exhibited a maximum luminance of4205 cd/m2 and a maximum current efficiency of 7.58 cd/A.
