Abstract: | This paper reports that nanoporous AlN particles are synthesized
from solid-state metathesis reactions using AlCl3 and
Mg3N2 as reactants. The samples are characterized by x-ray
diffraction (XRD), transmission electron microscopy (TEM), selected
area electron diffraction, high-resolution transmission electron
microscopy (HRTEM), ultraviolet--visible (UV--vis) absorption
spectroscopy and Raman spectroscopy. The results show that
samples with walls 10 nm in thickness and pores between 10 nm and
100 nm in diameter were produced successfully from these reactions, and
their band gap and vibration modes agree with those of AlN bulk
crystal. |
