Nanocrystals In Inorganic Matrices: Materials With Robust Performance

The incorporation of colloidal quantum dots (QDs) into sol-gel oxide matrices as well as into ionic crystals of various ionic salts is demonstrated. The resulting all-inorganic composites preserve the strong luminescence of the incorporated QDs. Moreover, the inorganic materials appear to be very robust matrices, ensuring the protection of the QDs from the environment and as a result providing them with extraordinary high photo-, thermal and chemical stability. Application potential of such kind of nanostructures for optoelectronics is discussed.
