Pb(NO3)(2) and Na2S were respectively dissolved in solvation layer af
Triton X-100/C10H21OH/H2O lamellar liquid crystal. Mixing up the two l
iquid crystal systems could synthesize fine particles PbS in the solva
tion layer. The synthesis was based on the limitation of the change of
thickness of solvation layer in the lamellar liquid crystal. The size
of fine particle PbS thus synthesized was less than 10 nm, and changi
ng the related composition concentration didn't much affect the size o
f fine particles PbS.
