X-ray emission spectra from aluminum clusters of diameter 0.4 μm and gold clusters of dia. ～1.25 μm are experimentally studied by irradiating the cluster foil targets with 1.06 μm laser, 10 ns (FWHM) at an intensity ～10{sup}12 W/cm{sup}2. Aluminum clusters show a different spectra compared to bulk material whereas gold cluster evolve towards bulk gold. Experimental data are analyzed on the basis of cluster dimension, laser wavelength and pulse duration. PIC simulations areperformed to study the behavior of clusters at higher intensity I ≥10{sup}17 W/cm{sup}2 for different size of the clusters irradiated at different laser wavelengths. Results indicate the dependence of cluster dynamics on cluster size and incident laser wavelength.
