  The interaction between carbon nanostructures like quantum dots and radiation
can generate different effects inside the nanomaterial, with the use of
computational methods such effects can be predicted and optimize the material
allowing a desired output. In this work, a theoretical model for pristine
graphene quantum dots is studied, allowing to explain the shape and size
dependence for the electronic properties and how the bandgap can be tuned with
the functionalization of the nanostructure at the edges.
