| Outline of Final Research Achievements |
It was performed that the investigation of mechanism of electro-luminescence and improvement of device properties for near UV light emitting diodes using nitrogen doped ZnO nanoparticle layers deposited on n-type ZnO films. The observation of hole injection from p-type nanoparticles to n-type layers, the improvement of the yield of p-type nanoparticles preparation and reduction of leak current and temperature were accomplished. The brightness of the particles with luminescence was comparable to that of commercial near UV LEDs, though the total power was still weak.
