چکیده انگلیسی
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.
