A simple and straightforward approach was devised to fabricate microspherical aggregates of alumina nanoparticles by self-assembly. Two different organosilanes were used as surfactant agents. Spherical aggregates were spin-coated on a silicon substrate. Spheres with diameters ranging from 100 nm to a few micrometers were thus assembled within an hour. The spatial distribution and the size distribution of the spheres are adjustable by changing the concentration of used organosilane. Effects of different organosilane agents, mixture molarity, and temperature on the size distribution of the spheres were also investigated.
