Abstract

Silicon clusters have garnered significant interest due to their unique physical and chemical properties, which make them valuable in fields such as nanotechnology, optoelectronics, and materials science. The purpose of this research is to investigate the effects of beta and gamma irradiation on silicon clusters, with a particular emphasis on gaining a knowledge of how irradiation over varying time intervals contributes to the molecular interactions and spectral features of silicon clusters. The ambient pressure and the two-step acid-base catalysis were both reliant on the manufacturing process. Beta and gamma radiation were used as sources at 2, 4, and 6 hours. The work combines spectroscopic analysis with molecular interaction assessments, and it makes use of FTIR analysis, N2 adsorption-desorption, FESEM, and EDS in order to shed light on the behavior of silicon before and after it has been irradiated in varied concentration clusters across time. Based on the findings, it was determined that the samples that were subjected to gamma radiation did not exhibit any discernible changes in their chemical structure, pore structure, or even surface appearance. Beta irradiation was applied to the samples for a period of six hours, and after that, there was a small alteration in the pore structure of the sample, the surface area decreases from 851.02 before irradiation to 833.03 at Beta Rad. This decrease occurred due to gamma radiation. The reduction was minimal. After irradiation, the pore size decreases from 10.44 to 0.9 and 0.8, while the pore volume, particle size, and pore diameter increase. The FE-SEM images show morphological stability; indicates that its unique porous nanostructure remains largely unaffected under radiative stress. The study comes to the conclusion that silica aerogel is a material that has the potential to be used in radiation isolation.
