摘要

本文报道了激光液固相互作用(LLSI)合成的具有Nd:YAG基频的Pt、Ag、Au和Cu纳米悬浮液的稳定性。从溶剂的极化指数、局部电分子偶极子和粘度等方面考察了金属纳米粒子在水、乙腈和戊烷三种不同分散液体中的稳定性。这些参数分别在0.0-10.2 PI、0.0-3.44 Debyes和0.23-1.0 cP范围内变化。金属纳米粒子在分散剂中的稳定性主要通过其各自在紫外可见光谱范围内出现的表面等离子体峰来研究。

Pulsed laser liquid-solid interaction synthesis of Pt, Au, Ag and Cu nanosuspensions and their stability
This paper reports on the stability of Pt, Ag, Au and Cu nanosuspensions synthesised by Laser Liquid-Solid Interaction (LLSI) with the fundamental Nd:YAG frequency. The stability of the metallic nanoparticles in three different dispersing liquid agents, namely, water, acetonitrile and pentane, has been investigated in terms of the solvents' polarisability index, local electric molecular dipole and viscosity. These parameters were varied within the following value range: 0.0-10.2 PI, 0.0-3.44 Debyes and 0.23-1.0 cP, respectively. The stability of the metallic nanoparticles within the dispersing agents was mainly investigated via their respective surface plasmon peaks which occur in UV-VIS spectral range.
