Facile synthesis of SnS hollow nanoparticles via laser ablation followed by chemical etching

Abstract

SnS hollow nanoparticles (HNPs) were fabricated by a two-step method, where laser ablation of a Sn target was first conducted in ethanol solution of thioacetamide to synthesize Sn@SnS core-shell nanoparticles, and then acid etching was employed to eliminate the Sn cores. The as-obtained SnS HNPs are uniform and nearly spherical with a size of y40 nm. Moreover, the shell thickness of the HNPs can be facilely modified by adjusting the concentration of thioacetamide in the first step.

“…Nanocolloids synthesis was completely free of any ligands and was highly stable. Other materials having applications in solar cells and optoelectronics synthesized by PLALM include ZnS [16], PbS [16], SnS [17], CdS [18], Sb 2 S 3 [19], CdTe [20,21], CdSe [21,22] and ZnTe [21]. Here we report synthesis, morphology and properties of CIGS nanoparticles using pulsed laser ablation of a CIGS alloy target in different liquid media by varying the laser fluence and ablation wavelengths.…”
