In the past two decades,
advances in synthetic methodology have led to the preparation of
a wide variety of high-quality nanocrystals with well-controlled
size, shape, and composition.

The shape of these high-quality
nanocrystals includes spheres, as well as nonspherical structures
such as cubes, plates, prisms, and rods.
