Abstract

Approximately spherical nanoparticles of the II–VI semiconductor materials Zn1 – xCdxS have been produced successfully by laser ablation of the bulk material in several liquids. The non-stabilized suspensions of particles are characterized by absorption spectroscopy and transmission electron microscopy (TEM). The procedure is not strongly size-selective, radii of 7 ± 3 nm were found for Zn1 – xCdxS by transmission electron microscopy. Acetonitrile stabilizes the particles for several days up to weeks. Prolonged irradiation leads effectively to a reduction in particles size, in which particle agglomeration may play an important role. Ablation in degassed liquids does not have a significant effect on the absorption of the suspended particles.

激光烧蚀获得的Zn 1 – x Cd x S纳米粒子

摘要

II-VI半导体材料Zn 1-  x Cd x S的近似球形纳米粒子已通过激光烧蚀几种液体中的块状材料而成功制备。颗粒的非稳定悬浮液通过吸收光谱和透射电子显微镜(TEM)表征。该过程不是很强的尺寸选择,发现Zn 1 –  x Cd x的半径为7±3 nmS通过透射电子显微镜观察。乙腈可将颗粒稳定几天至几周。长时间的照射有效地导致了颗粒尺寸的减小,其中颗粒的聚集可能起着重要的作用。脱气液体中的烧蚀对悬浮颗粒的吸收没有显着影响。
