We report on a new approach toward synthesis of Sm3+ doped TiO2 and Ni2+ doped
TiO2 nanocrystals by shape transformation of hydrothermally treated titania
nanotubes in the presence of Sm3+ or Ni2+ ions. The percentage ratio of Sm3+ (or
Ni2+) to Ti4+ ions in doped nanocrystals was determined using ICP atomic emission
spectroscopy. The XRD patterns revealed the homogeneous anatase crystal phase
of both 0.4 at% Sm3+ doped TiO2 and 0.12 at% Ni2+ doped TiO2 nanoparticles. An
average size of polyhedral Sm3+ doped TiO2 nanocrystals was between 12 and 14
nm. In the orange-red spectral region, room temperature photoluminescence signals
associated with 4
G5/2 →6
HJ (J = 5/2, 7/2 and 9/2) transitions of Sm3+ was observed
in Sm3+ doped TiO2 nanocrystals. Optically transparent film made of 0.12 at% Ni2+
doped TiO2 nanoparticles showed room temperature ferromagnetic ordering. The
coercive field was found to be HC ~ 80 Oe.
