CdS nanoparticles are synthesized in reversed micelles which are then
subjected to enhanced pressures of a light hydrocarbon gas. At lower t
emperatures. clathrate hydrates form. reducing the micellar water cont
ent. The particles remain in solution until a critical phase transitio
n pressure. The removal of water leads to an enhancement in particle s
tability and a resistance to photocorrosion. It is thus possible to pr
epare CdS particles of various band gap energies and to stabilize thes
e particles subsequently, through a process of water removal and micel
le size reduction.
