This activity leads students through the synthesis of compound nanoparticles and examines how key physical properties such as band gap vary with particle size. Prior to doing this, students should have some exposure to the structure of solids, band theory, and band gap as a periodic property (see, for example, Lisensky, et al. J Chem.
In the past, I've always found the IUCr crystallographic pamphlets to be useful when teaching diffraction. They've reorganized their website to make their educational resources easier to find. On this link, you can find the IUCr teaching pamphlets, a short description of how to grow crystals, and other crystallography web resources.

In this lab experiment, students use sol-gel chemistry to prepare silica gel monoliths from tetraethylorthosilicate (TEOS). Carrying out the hydrolysis and condensation under acid-catalyzed vs.
JMol site http://firstyear.chem.usyd.edu.au/calculators/solid_state.shtml how common inorganic structures are built from the filling of interstitial sites in CCP and HCP lattices.
The site is used as post-work for a hands-on lab about packing (http://firstyear.chem.usyd.edu.au/LabManual/E12.pdf).
The Interdisciplinary Education Group at the University of Wisconsin Madison Materials Research Science and Engineering Center (MRSEC) has a fabulous website with a wide variety of great resources for teaching about materials and the nanoworld at all levels. A favorite "corner" of this website that I refer to a lot in my own teaching is the library of so-called Resource Slides on a variety of topics. These Resource Slides are divided up into 36 topical Slide Shows and include wonderful graphics to use in class presentations. Slide Shows include:
The Interactive Inorganic Challenge Forum is a resource for inorganic chemistry teachers who want to incorporate team learning questions (“Challenges”) into an upper level undergraduate inorganic course. Through this site, teachers can exchange their ideas with others who have used inorganic chemistry Challenges. As a result, students benefit from field-tested group questions.
