研究目的
Investigating the fabrication of shuttle-shaped GaxCo0.6-xZnS0.4 nanoparticles using Magnetic Polarization Pulse Laser Ablation (MPPLA) method and comparing their properties with circular-shaped nanoparticles.
研究成果
The MPPLA method successfully fabricates shuttle-shaped GaxCo0.6-xZnS0.4 nanoparticles with improved structural and optical properties compared to circular-shaped nanoparticles. The method effectively addresses cluster problems and modulates nanoparticle performance, suggesting its potential for advanced nanomaterial preparation.
研究不足
The study is limited by the use of deionized water as the collection liquid due to the flammability of ethyl alcohol in laser processes, which may affect nanoparticle dispersiveness. Additionally, the external magnetic field's influence on nanoparticle shape and size distribution requires further optimization.
