An Investigation of Germanium Properties Prepared by Laser Ablation in Liquid
Iman H. Hadi
Abstract

In this work, fabrication and characterization of germanium (Ge) NP is presented. The germanium particles were prepared by pulsed laser ablation in liquid technique (PLAL) at different laser fluence using Q-switched Nd:YAG laser at (1.06 ┬Ám) laser wavelength with pulsewidth 10 ns .Atomic Force Microscopy(AFM) and Energy Dispersive Analysis of X-rays (EDAX) are utilized here to study the surface and sizes of Ge nanoparticles and the evidences for ablation of materials respectively and the spectrophotometer have been used to characterize the optical properties of the prepared nanoparticles .
Keywords: laser-ablation in liquid, Ge nanoparticles, nano-ablation, Colloids.
