© 2018 The Japan Society of Applied Physics. Perovskite materials are emerging as suitable materials for low-cost, high efficiency optoelectronics. In this study, we reported the surface modification of 2D (PEA) 2 PbBr 4 for violet emission using PEG doping followed by a newly developed step called...
