RESUMO

Nanotechnologies and nanomaterials are very current and interesting topics and can be used as interdisciplinary tools in education. They can be used to work in a practical and interesting way with lots of subjects. In chemistry teaching it can be particularly important to consolidate the nanomaterials, nanotechnology and characterization teaching. Among the nanomaterials, quantum dots (QDs) can be highlighted due to their interesting optical and electronical properties. Some of the topics that can be discussed related to them are the nanoparticles synthesis, spectroscopies and optical characterization, X-ray diffractometry and structural characterization, surface ligands, semiconductor materials, electronic transition, solid crystalline structure, colloidal synthesis, among many other subjects. The application of the experiment of synthesis and characterization of environmentally friendly quantum dots to students of the discipline “Solid State Chemistry” of the chemistry undergraduate course, allowed the contact of students with materials of great technological interest. Being a material widely studied by various research groups around the world. The experiment proved to be an interesting way to introduce students to a material of great technological interest, in a simple and accessible way. It aroused the interest of the students while allowing the practical application of the acquired knowledge.
