“…It is well known that nanoscale materials, owing to their size and morphology, have outstanding properties that differ substantially from their bulk counterparts [1][2][3]. Specifically, nanosize metals such as gold and silver have also been recognized to exhibit novel size-dependent optical properties [4][5][6][7].…”

An innovative design has been proposed to develop the synthesis of laser ablated gold nanoparticles in pure water, by co-radiation of Nd : YAG laser pulses and ultrasound waves. UV–VIS absorption spectroscopy illustrated the enhancement of the synthesis rate of the particles in the diversity of laser pulse energies applied in the presence of ultrasound waves. In addition, the proliferative effects of laser pulse energy on the synthesis rate and the size of particles were recognized as well. Emission spectroscopy of the induced plasma was utilized to justify the variation of the synthesis rate versus the applied operating conditions. Electron microscopy as a complementary technique confirmed the results of spectroscopic findings concerning the enlargement of nanoparticles by laser pulse energy.

“…The structural and physical properties of small alkali halide clusters differ significantly from bulk behavior . Alkali halides have ability to form stoichiometric (MX) n and non‐stoichiometric such as M n X and M n X n‐m (M ‐ alkali metal atom, X ‐ nonmetal, n > m) heterogeneous clusters . The non‐stoichiometric clusters with single or multiple ‘excess’ metal have been of large interest as prototypes for the study of a possible ‘metal–insulator’ (delocalization–localization) transitions with evolution of a cluster size or variation of chemical composition.…”

The theoretical calculations have predicted that nonmetal-doped potassium clusters can be used in the synthesis of a new class of charge-transfer salts which can be considered as potential building blocks for the assembly of novel nanostructured material. In this work, K(n)Cl (n = 2-6) and K(n)Cl(n-1) (n = 3 and 4) clusters were produced by vaporization of a solid potassium chloride salt in a thermal ionization mass spectrometry. The ionization energies (IEs) were measured, and found to be 3.64 ± 0.20 eV for K(2)Cl, 3.67 ± 0.20 eV for K(3)Cl, 3.62 ± 0.20 eV for K(4)Cl, 3.57 ± 0.20 eV for K(5)Cl, 3.69 ± 0.20 eV for K(6)Cl, 3.71 ± 0.20 eV for K(3)Cl(2) and 3.72 ± 0.20 eV for K(4)Cl(3). The K(n)Cl(+) (n = 3-6) clusters were detected for the first time in a cluster beam generated by the thermal ionization source of modified design. Also, this work is the first to report experimentally obtained values of IEs for K(n)Cl(+) (n = 3-6) and K(n)Cl(n-1) (+) (n = 3 and 4) clusters. The ionization energies for K(n)Cl(+) and K(n)Cl(n-1) (+) clusters are much lower than the 4.34 eV of the potassium atom; hence, these clusters should be classified as 'superalkali' species.
