Among two-dimensional (2D) materials, black phosphorus (BP) has emerged as a promising material in photonics and optoelectronics due to its direct bandgap and layer-dependent photon emission in the mid- to near- infrared (IR) wavelength range. Previously, we successfully synthesized bulk BP inks for deposition of optoelectronic devices via aerosol jet printing (AJP). In this work, we use density gradient ultracentrifugation (DGU) to isolate monolayer phosphorene from bulk BP solutions. Once sorted, we exchange the solvent of the monodisperse solution to AJP compatible solvents. Our solutions show good monodispersity and a photon emission wavelength of 620 nm. Our DGU model confirms the buoyant density range, DGU media, and surfactants required to isolate monolayer BP. This work demonstrates progress in processing bulk BP into monodisperse solutions for AJP of fine-tuned optoelectronic devices.
