Description

Hydrothermally synthesized rare-earth oxide compounds such as
Nd2O3, Dy2O3, Gd2O3, Eu2O3, Y2O3, etc. and hydroxide compounds such as
Y(OH)3, Dy(OH)3, Gd(OH)3, Eu(OH)3, Tb(OH)3, etc. have been widely used
as high-performance luminescent devices, catalysts and other functional
materials based on the electronic, optical and chemical characteristics arising
from their 4f electrons. In the crystallization process, surfactant molecules
adsorbed on the crystal nuclei serve not only as a growth director but also as a
protector to prevent from aggregation of the product. As a result, nanorods
were produced. Cetyl trimethyl ammonium bromide (CTAB) and
hexadecylamine (HDA) surfactant are plays a key role in controlling the
growth and production of oxide phosphors in the hydrothermal method.
