Investigation of energy band gap and the synthesis of silver nanoparticles.

This study includes a brief survey of the literature on silver nanoparticles synthesized by green methods. Where the green chemistry method was used to prepare silver nanoparticles, and the survey showed that different types of plants are promising for environmentally friendly treatment methods, properties, and possible uses as alternatives to silver nanoparticles. The paper lists the basic classes of nanomaterials and the advantages of the synthesis of nanoparticles extracted from fungi and bacteria. More details on the specific properties and bandgap energies of the nanomaterials can be found in the manuscript. The energy bandgap of AgNPs was formulated as a function of shape and size. The modeling theory was founded on the aggregation energy of Ag nanoparticles with respect to the crystal structure; We find that the energy bandgap of AgNPs depends on the particle shape and size. According to this model, as the particle size of nanostructured materials decreases, the energy gap is found to increase. The energy gap increases according to the results of this paper. This paper is based on various observations and supports the validity of Ag nanoparticles. [ABSTRACT FROM AUTHOR]
