We discuss our efforts in studying the light-matter interactions in halide-grown monolayer and few-layer 2D semiconducting WSe2 to unveil multibody interactions towards quantum platforms. Heterostructures of 0D-2D ensembles also offer an intriguing prospect to enhance the light matter interactions in these systems to new levels. When sheets of graphene are physically confined into nanoscale dimensions, either as graphene nanoribbons or zero-dimensional (0D) structures, such as graphene quantum dots (GQDs), a band gap in such structures is induced due to quantum confinement. We discuss the integration of GQDs and 2D MoS2 for optoelectronic devices surpassing the limitations of MoS2 photodetectors where the GQDs extend the optical absorption into the near-UV regime. Finally, our additive manufacturing approaches with organo-halide 2D perovskites, specifically, butylamine methyl-ammonium lead triiodide, opens up possibilities to inkjet print these complex crystallites and their heterostructures for exceptional optical absorbers in photodetectors and photovoltaics applications.
