| Abstract: | Langmuir-Blodgett (LB) films are formed by the successive deposition of one or more types of amphiphilic molecules initally spread at the inter- face between water and air.Laminated ploymeric LB alternative multilay- ers is kind of stable non-centrosymmetric matiral.X ray diffraction and SHG measurement showed good evidence for that some alternating system containing fatty acid have good order with repeat distance corresponding to the expected-superlattice.These finding will be useful in selecting systems for future non-linear optios applications. |
