Wz. Wang et al., A novel and simple one-step solid-state reaction for the synthesis of PbS nanoparticles in the presence of a suitable surfactant, MATER RES B, 36(11), 2001, pp. 1977-1984
A novel and simple one-step solid-state reaction in the presence of a suita
ble surfactant has been developed. We have synthesized PbS nanoparticles wi
th the diameters of ca. 10-15 nm by using this method. The PbS nanoparticle
s were characterized by X-ray diffraction (XRD), transmission electron micr
oscopy (TEM), high-resolution transmission electron microscopy (HRTEM), UV-
VIS optical absorption, and X-ray photoelectron spectrum (XPS). The roles o
f surfactant C18H37O(CH2CH2O)(10)H (abbreviated as C18EO10) in the forming
of PbS nanoparticles were discussed, and the results indicated that the sur
factant C18EO10 played an important role in the preparation of PbS nanopart
icles. (C) 2001 Elsevier Science Ltd. All rights reserved.
