Size-dependent radiative decay processes in graphene quantum dots

(author unknown)



Sung Kim, Dong Hee Shin, and Chang Oh Kim et al.

Radiative decay processes have been studied in graphene quantum dots (GQDs) by varying their size. The photoluminescence (PL) decay traces are well fitted to a biexponential function with lifetimes of τ1 and τ2, indicating their fast and slow components, respectively. The τ1 is almost constant, ir ... [Appl. Phys. Lett. 101, 163103 (2012)] published Tue Oct 16, 2012.
