Abstract: CdSO4 and (NH4)2S were separately dissolved in solvation layer of Triton X-100/C10H21OH/H2O lamellar liquid crystal. The mixing of the two liquid crystal systems resulted in the formation of ultrafine CdS particles in the solvation layer.The size of CdS particles was limited by the change of thickness of solvation layer in the lamellar liquid crystal to be less than 10 nm in diameter. Changing the related component concentrations did not considerably affect the size of ultrafine CdS particles.

Key words: ultrafine particle, lamellar liquid crystal, surfactant, Triton X-100, CdS
