Some 35 years ago the so-called size quantization in semiconductor nanocrystals has been found and explained correctly. Since then enormous progress has been made in various directions: quality of the materials (measured as size dispersity, crystallinity, compositional variability, surface functionalization, etc.), applications (in lighting, bioenvironments, solar cells, etc.), as well as basic theoretical understanding.

I will touch upon a few of these developments in more detail and, quite naturally, from my personal point of view and experience. One of these developments which spans a period of about a decade is that of unraveling the mechanisms of emission in II-VI semiconductor particles of different compositions.

Here and there I will also touch upon modern methods of creating superstructures (mesocrystals, aerogels) from nanocrystals and by this marrying the nano- to the macroworld.
