摘要：
A modified pulsed laser deposition (PLD) was successfully employed to deposit GaAs nanocrystals on the surface of PMMA (polymethylmethacrylate) microspheres. This novel approach is distinguished by the fact that laser ablated materials are deposited uniformly onto the surface of spherical particles that are held constantly in a particle fluidization unit. The XRD, SEM, EDX, TEM, EDP, and XPS results confirmed that cubic structured GaAs nanocrystals was deposited uniformly on the surface of PMMA microspheres with an average diameter of about 15 nm.
