In this contribution, we present a facile and well-controlled synthesis of GaN nanodisks by rapid thermal ammonolysis of complex gallium fluoride precursor. We observed the formation of GaN nanodisks in 150 s at 800 degrees C. The structural properties of GaN were investigated by X-ray diffraction, Raman spectroscopy, and micro-photoluminescence. The morphology of GaN was investigated by scanning electron microscopy and the magnetic properties by superconducting quantum interference device (SQUID) techniques. The morphology of nanodisks was strongly influenced by the temperature of synthesis. The structure characterization shows a high concentration of defects related mainly to the vacancies of N and Ga. The magnetic measurement by SQUID shows paramagnetic behavior induced by structure defects. These findings have a strong implication on the construction of modern optoelectronic nanodevices.
