AbstractSuperlattices of nanoparticles are generally produced based on solution chemistry processes. In this paper, we demonstrate that self-assembled monolayer structures of nanoparticles with superlattice periodicities can also be produced on template-free surfaces in the gas-phase cluster beam deposition process. It is found that the packing of Fe nanoparticles corresponds to an average of two-dimensional densely packed lattice with a hexagonal summary. By controlling the nanoparticle coverage, the two-dimensional densely packed monolayer morphology can spread to the whole substrate surface being deposited. A formation mechanism of the ordered monolayers is proposed. The densely packed morphologies are formed by the balance between the diffusion rate of the nanoparticles and their filling speed on the substrate surface determined by the deposition rate, and the ordering of the nanoparticle arrays is driven by the inter-particle attractive interactions. The model is strongly supported by a series of carefully designed cluster deposition experiments.

Series samples Zn(1-x)S:Cux (0.001<x<0.05) have been prepared by a simple and template-free microemulsion method. From the XRD we know that all samples are single phase. The SEM photo shows that the particle sizes are about 50～200nm.When the contents of doping Cu2+ ions increasing, the particle sizes become larger, which proves that Cu2+ ions occupy the position of Zn2+ ions. The emission spectrum (ES) indicates that when doping Cu2+ ions ,samples show a blue light and the main emission peaks which caused by Cu2+ ions t2 transition locates at 425nm. Moreover, when co-doping Cu2+ ions and Mn2+ ions, the intensity of PL emissions increased.
