Device, System, and Method for Selectively Tuning Nanoparticles with Graphene

A method of filtering color by way of a graphene device, comprising:

• providing the graphene device, providing the graphene device comprising:
• providing a graphene structure responsive to continuous in-situ electrical gate-tuning of a Fermi level thereof;
• and
• providing a plurality of nanoparticles disposed in relation to the graphene structure, providing the plurality of nanoparticles comprising providing each portion of the plurality of nanoparticles with a distinct energy bandgap in relation to another portion of the plurality of nanoparticles, and providing the plurality of nanoparticles comprising configuring each portion of the plurality of nanoparticles to one of activate and deactivate in relation to the distinct energy bandgap and in response to the in-situ electrical gate-tuning of the Fermi level of the graphene structure;
• continuously in-situ electrical gate-tuning the graphene structure by an externally applied gate bias;
• and
• one of activating and deactivating each portion of the plurality of nanoparticles in relation to the distinct energy bandgap and in response to the in-situ electrical gate-tuning of the Fermi level of the graphene structure, thereby filtering color.
