"enhance signal in CsPbBr3 using patterned waveguide based on polyurethane-acrylate... improved optical confinement and heat dissipation facilitated by 2D center-of-mass confined excitons and localized states arising from inhomogeneous sheet thickness and defect states... solar cells, neuromorphic computing, communication (lasers), optical probes and sensors (photodetectors)... consumer products like smartphones and lighting, would depend on overcoming challenges related to stability, scalability, and toxicity"
