摘要

This work presents an analysis of the optical properties of transition metal adatom-graphene quantum dot complexes (TM-GQDs). TM-GQDs with five metals (Cr, Mo, W, Pd, and Pt) and pristine GQDs were investigated to explore the possibility of engineering the optical characteristics. By Density Functional Theory and Time-Dependent Density Functional Theory, excited energy states and absorption spectr...
