Studies of Plasmonic Gold (Au) Nanoparticles and Nanofilms Effects on Photoelectron Generation Using B₂O₃ Glass Substrate

Au nanoparticles are known for substantially modifying their properties depending on the particle size. In the field of radiotherapy, the interaction of low-energy X-rays with high-Z plasmonic nanomaterials endow them with the ability to sensitize radiotherapy. In this study, Au nanofilms and nanoparticles were deposited on a B₂O₃ glass substrate using an electron beam evaporation technique and bombarded with X-ray at 150 kVp at 1 mA. Thermoluminescent (TL) measurement responses were measured using thermoluminescence dosimetry (TLD). The assembled structure with tunable properties leads to versatile applications in drug delivery and cancer treatment which is beneficial in the health treatment industry.
