Preparation And Characteristics Of Mg-Al_0.09-Zn_0.01 Nanoparticles Deposited On Silicon Nanostructure For Photo-Conversion Application

The paper studies the use and properties of Mg-Al_0.09-Z n_0.01 magnesium alloy in photo-conversion application. Magnesium alloys have excellent specific strength, stiffness, damping vibrations, and recyclability, making them highly desirable in industries such as automotive, aerospace, and electrical consumer devices. Also, the use of nanoparticles in various applications and how they exhibit physical, chemical, and biological characteristics due to their small size compared to their corresponding particles at larger scales. This paper presents the results and discussion of the experimental study conducted on Mg-9%wt.Al-1%wt.Zn nanoparticles prepared by laser ablation synthesis. The study primarily focused on investigating the structural, optical, and electrical properties of the nanoparticles. The XRD analysis showed the characteristic peaks of magnesium (Mg) and magnesium oxide (MgO), and the SEM images display the morphology of the particles that depend on the energy of the laser pulse. The optical absorption spectrum was measured, and the optical band gap energy was computed, revealing an increase in band gap as laser intensities increased. The current-voltage characteristics of the photodetector and electrical properties were also measured, indicating the increase in conductivity of the Mg-9%wt.Al-1%wt.Zn nanoparticles compared to porous silicon. Overall, the results and discussion provide important insights into the properties and potential applications of Mg-9%wt.Al-1%wt.Zn nanoparticles prepared by laser ablation synthesis.
