Abstract: Under the conditions of the higher surface pressure and deposition speed, ordered organic/CdSnanoparticles complex film was prepared by the reaction of cadmium stearate and H2S."All trans" conformation of -CH2- can be kept well after reaction which is thought to form nanoorder organic-inorganic superlattice material.Bragg (001) diffraction peaks can be observed by means of X-ray diffraction related to 5.02 nm of the long period.The order property of LBcomplex film was shown according to the result of infrared spectrum.The band gap (Eg) of CdSnanoparticle is 3.46 eVwhich increases 1- 04 eVcomparable to that of the bulk material(2.42 eV) from the result of UV-Vis spectrurn.
