N2 - Integrating 2D and 0D materials gives rise to hybrid systems with unique and attractive properties. This work explores the successful assembly of large area heterostructures comprised of a film of luminescent colloidal quantum dots encapsulated in a silica shell, deposited via the Langmuir-Blodgett method, sandwiched between two graphene sheets. Despite significant experimental challenges, the structural, optical and electronic properties of the graphene and quantum dots were maintained. The top graphene sheet was patterned into an electrode, and successfully used as a top gate for an underlying graphene field effect transistor, paving the way for developing novel optoelectronic devices.
