One of the features of crystals with nano-scale size, which are isolated in a polymer matrix, is essential chemical activity of their surface. This fact can be used in many applications (e.g., while creating different types of sensors and catalysts of chemical reactions) and, in the scientific aspect, in oder to study the physics of surface states at the interfaces between two different phases.

Key words: nanocrystals, luminescence, the size effect.
