Optical characterization of sol-gel-derived SnO2:Eu nanopowders annealed at high temperatures

Nanoparticulate SnO2 powders doped with europium (0.5 at%) were prepared by using sol‐gel method. The samples were sintered in air or argon at temperatures ranging from 600 to 1400 °C. Raman‐, SEM‐ and photoluminescence characterization of the samples was carried out. The heat‐treated samples expose...
