| Abstract |
Nanohybrids of zinc selenide and smectites (a natural montmorillonite and a synthetic saponite) were prepared
by a hydrothermal reaction of zinc chloride and sodium selenosulfite in the presence of smectites. The products
were characterized by powder X-ray diffraction, scanning and transmission electronmicroscopies, thermogravimetric
analysis, as well as, UV–visible and photoluminescence spectroscopies. The round-shaped zinc selenide
nanoparticles with the average diameter of 1–4 nm formed in the interlayer space of smectites, which gave
the absorption onsets at 379–456 nmfor montmorillonite systemand at 475 nmfor saponite system. Additional
absorption onsetswere observed at around 478–665 nmfor montmorillonite systemand at 609–682 nmfor saponite
system, suggesting the larger-sized particles formed at the external surfaces. The photoluminescence observed
in the wavelength range of 357–360 nm was interpreted to the formation of zinc selenide
nanoparticles in smectites. The increase of the photoluminescence intensities of all the products (from 35 for
bulk ZnSe to 126–294 for ZnSe(n)-smectites) was thought to be caused by the interactions with smectites
and/or size and shape of ZnSe formed in the hybrids. |
