Metoda zol-żel jest stosowana w Instytucie Technologii Materiałów Elektronicznych (ITME) do otrzymywania nanoproszków wieloskładnikowych tlenków. W pracy jest opisane znaczenie nanoproszków dla zastosowań w optoelektronice i fotowoltaice. Przedstawiono opis procesu metody zol-żel na przykładzie granatu Y3Al5O12 (YAG). Wykazano, że proces zachodzi na drodze reakcji chemicznej w niskiej temperaturze i temperaturze prażenia ok. 1000°C. W rezultacie otrzymuje się materiały bardzo czyste, o wysokiej stechiometrii. Omówiono badania luminescencji dla YAG:Nd oraz Y4Al2O9 (YAM):Yb i Nd i GdCa4O(BO3)3 (GdCOB):Eu. Pokazano, że czasy zaniku luminescencji badanych nanoproszków są dłuższe niż te obserwowane w monokryształach. Szczegółowe wyniki są przedstawione w cytowanych publikacjach.

The sol-gel method is used to obtain nanopowders of polycomponent oxides at Institute of Electronic Materials Technology. The role of nanopowders in optoelectronics and photovoltaic technology is described. The garnet of Y3Al5O12 (YAG) is used to describe the details of sol-gel procedure. It is shown that the process is going by chemical reactions at low temperature and annealing at about 1000°C. Nanopowders of compound are very high purity and stoichiometry. Some results of luminescence of YAG:Nd, Y4Al2O9 (YAM):Yb and Nd and GdCa4O(BO3)3 (GdCOB):Eu are presented. It is shown that decay life times are longer for nanopowders than these for single crystals. The detailed results are presented in our cited publications.
