Thin film light-emitting diodes with organic/inorganic heterostructure in which ZnO:Zn layer was used as electron transporting and hole blocking layer, PDDOPV, Poly(2,5- Didodecyloxy-1,4 Phenylenevinylene ) was used as hole transport and emission layer have been successfully prepared. Comparing to single layer device, the luminescent efficiency of bilayer device is improved about twenty-six times, the emission spectrum's peak wavelength shifts to short wavelength, the half width at full maximum (HWFM) widens. The improvement of luminescent efficiency is due to the insertion of ZnO:Zn layer.
