Abstarct: This thesis is baxsed on synthesis and study of optical properties of AlN 1D nanostructures. The AlN nanostructures were grown in a triple zone 1800 ℃ electric furnace at N2 and Ar atmosphers. The raw materials were mixture of Al and NH4Cl powders as baxsed materials and Mn and Cu powders as dopant. The samples were grown at different conditions. Structural studies have been done by FE-SEM. results confirmed the formation of different nanostructures includes: nanowires, nanoparticles and nanocages. Photoluminescence properties of as-prepared samples were investigated with UV lamp and He-Cd laser as excitation source with excitation wavelength of 360nm and 325nm respectively. The results show three peaks in blue, green and red region with good intensity at room temperature. The intensity of PL spectrums increased after annealing in N2 for 30min or Ar atmosphere for 60 min respectively. This intensive emission in three primary colors from AlN nanowires at room temperature is important in optoelectrical applications like displaxyers and LED applications.
