SCSU Journal of Student Scholarship

ZnO nanoparticles exhibit attractive optical properties that are important in the realm of catalysis and nanotechnology involving the developments of solar cells, chemical sensors and other optoelectronic devices. The main objective of this project was to create zinc oxide nanoparticles of less than 10 nm size by using an Nd: YAG laser and characterize the particle diameter. Zinc oxide nanoparticles were prepared by vaporizing zinc in neat deionized water by laser ablation, aided by a physical 2D-motional micro-stage programmed by Arduino. The addition of surfactant was explored to reduce aggregation of the nanoparticles. Various purification methods were applied to this …
