Description
Summary:The inclusion of nanoparticles in technological development increases every year. For example, metallic nanoparticles are applied in cosmetics, medicine, and sensing areas among others. When light interacts with metallic nanoparticles, the Localized Surface Plasmon Resonance (LSPR) can occur. LSPR is the subject of advanced courses in Physics and some of the students could have several difficulties in its comprehension. To benefit the students, it is proposed a very simple simulator built in Python to study the influence of the features of metallic spherical nanoparticles and of the host medium in the LSPR effect through the Mie Theory. A inclusão de nanopartículas no desenvolvimento da tecnologia se expande continuamente. Nanopartículas metálicas já são usadas em cosméticos, na área médica e em sensoriamento, dentre outras. Quando um feixe de luz interage com nanopartículas metálicas a Ressonância de Plasmons de Superfície Localizada (em inglês, LSPR) pode ocorrer. A LSPR é assunto de disciplinas avançadas em cursos de Física e alguns estudantes podem apresentar dificuldades em compreendê-la. Com o intuito de ajudar esses estudantes, é proposto um simulador simples, construído em Python para estudar a influência das características das nanopartículas metálicas e do meio que as circunda na LSPR através da Teoria de Mie.
