| 英文摘要 | Co-doped AlN hexagonal nanostructures were synthesized at different temperatures by a facile thermal chemical vapor deposition method. The products exhibit excellent temperature-dependent growth, photoluminescence and ferromagnetic properties. It is found that higher temperature not only facilitates Co incorporation but also increases the density of AlN nucleus, as a result, the morphologies of AlN nanostructures evolve with the increase of temperature. Two photoluminescence bands of samples are centered at 550 nm and 425 nm, which originate from defects involving VN and O impurities. Co doping may modulate the relative intensity of the emission bands by changing the states of impurities. All Co-doped AlN nanostructures show strong ferromagnetic behaviors which strongly depend on the Co concentration. It is indicated that the multifunctional Co-doped AlN nanostructures have potential applications in optoelectronic and DMSs devices. |
