The nanostructured oxide materials such as ZnO, ZrO2, and Y3Al5O12 (YAG) are perspective materials for transparent scintillating and/or
laser ceramics. The luminescence properties of single crystals, nanopowders and ceramic were compared. Nominally pure and rare-earth doped
nanopowders and ceramics have been studied by means of time-resolved luminescence spectroscopy.
The fast blue luminescence band was studied in ZnO ceramics sintering from different raw materials.
The luminescence centres of ZrO2:Y were compared in a single crystal, ceramic and nanopowder.
It is shown that ceramic sintering parameters have a strong influence on time-resolved luminescence characteristics in cerium-doped YAG.
