摘要: Neutral and charged phosphorus clusters of a wide size range have been produced by pulsed laser ablation (PLA) in vacuum at 532, 337, 193 nm ablating wavelengths investigated time-of-flight mass spectrometry. The neutral Pn are even-numbered with local abundance maxima n=10 14, while the cationic anionic preferentially odd-numbered P7+, P21+, P17- being most abundant ions. dominance magic is more pronounced 337-nm that explained efficient direct ejection their building blocks under these conditions. Nanocrystalline films PLA ambient helium gas.
