| Título: | Generation of CdS clusters using laser ablation: The role of wavelength and fluence |
Autor: | López-Arias, M.; Álvarez Ruiz, J.; de Nalda, R. ; Martín Muñoz, Margarita CSIC ; Arregui, Andrés; Bañares, Luis CSIC ORCID | Fecha de publicación: | 24-sep-2007 | Citación: | IX Conference on laser ablation (2007) | Resumen: | The generation of cationic CdS clusters by laser ablation was studied using a reflectron TOFMS. The analysis was carried out in the visible and the UV and at a broad range of laser fluences. The mass spectra revealed the presence of stoichiometric CdnSn (n=1-34) and CdnSn+m (m= -1,1,2,3) clusters. Cd34S34 was also detected, supporting previous work which identified n=13 and 34 as ultrastable magic numbers for chalcogenide clusters. We observed a significant decrease in the heavy to light mass ratio with UV irradiation, which suggests different mechanisms across the spectrum. | Descripción: | Trabajo presentado en el IX International Conference on Laser Ablation, celebrado en Tenerife (España) el 24 de septiembre de 2007. | URI: | http://hdl.handle.net/10261/258733 |
