Abstract: By transferringMgxZn1-xOsol and stearic acid onto a hydrophilic silicon wafer or glass plate, the Langmuir–Blodgett (LB) multilayers ofMgxZn1-xO(x:0, 0.2, 0.4) were deposited. After calcinations at 350°C for 0.5 h and at 500°C for 3 h,MgxZn1-xOultrathin films were fabricated. The optimized parameters for monolayer formation and multilayer deposition were determined by the surface pressure-surface (Π-A) area and the transfer coefficient, respectively. The expended areas of stearic acid withMgxZn1-xOsols under Π-Aisotherms inferred the interaction of stearic acid withMgxZn1-xOsols during the formation of monolayer at air–water interface. X-ray diffraction (XRD) was used to determine the crystal structures ofMgxZn1-xOnanoparticles and ultrathin films. The surface morphologies ofMgxZn1-xOultrathin films were observed by scanning probe microscopy (AFM). And the optoelectronic properties ofMgxZn1-xOwere detected and discussed based on photoluminescence (PL) spectra.
