According to the autocorrelation function (ACF) of dynamic light scattering (DLS) signals, the exponential model used for scattering signal simulation can be established. Based on this model, nine kinds of DLS signals for unimodal, bimodal and trimodal distribution particles are simulated respectively. The ACF of the simulated signal agrees with its theoretical value very well. Inverted size errors...
Un-hydrogenated Diamond-like Carbon (DLC) films were prepared by pulsed laser deposition technique at different substrate temperature. The Raman spectra, the absorption and the photoluminescence spectra were measured. The dependence of structure and photoluminescence properties on deposition temperature were studied in detail. The experimental results indicate that the sp2 sites form small clusters...
