Graphene can also emit some form of photoluminescence. Under an applied electrical field, the low density of states near the Dirac point causes the Fermi level of the graphene to shift.

Graphene/graphene oxide systems exhibit electrochromic behavior, allowing tuning of both linear and ultrafast optical properties. For tuning the optical transmission of an electromagnetic radiation source, a greater degree of absorption results in a lower optical transmission, and vice versa. 2020.

Graphene can also adsorb this radiation independent of its frequency because it doesn’t have discrete energy band levels like most materials. Because graphene possesses some unique optical properties and can absorb a wide range of electromagnetic radiation, there are a lot of potential optical and photonics applications that graphene can be used in, from saturable absorbers to transparent conductors in photonic devices and high-bandwidth photodetectors. It demonstrates that BC2O can induce a red shift of absorption spectra, while the absorption spectra of the surface doped GQD with BCO2 exhibits a blue shift. But graphene also has many other specific properties when it interacts with electromagnetic radiation. For example, a single layer of graphene only absorbs 2.3% of light, so 97.7% of light passes through a single layer, with around 0.1% reflected from its initial trajectory.
