Nanowerk  March 15, 2023 Perovskites is a promising material for producing 2D monolayer nanosheets if their tunability of bandgap corresponding to the energy of visible light. To solve this problem researchers in Japan focused on a Ruddlesden–Popper (RP) phase layered perovskite oxynitrides and successfully created 2D perovskite oxynitride nanosheets with a tunable bandgap using their novel process. The material had a homogenous thickness of 1.6 nm and exhibited different colors, ranging from white to yellow, depending on the nitridation temperature, and exhibited the semiconductor property of having a tunable bandgap in the visible region, ranging from 2.03-2.63 eV, based on […]
