摘要

This research investigates the intercalation of the rare earth element cerium (Ce) into the layered material (MnPS3) and the effect on its magnetic and optical properties. The magnetic and optical properties of MnPS3 were tested before and after intercalation with Ce. X-ray diffraction reveals a slight shift in the (001) phase due to intercalation of Ce. Scanning electron microscope with Energy Dispersive X-ray (SEM-EDX) reveals the layered structure morphology of MnPS3, and the presence of the Ce intercalated in the interlayer space. Magnetic behavior of the MnPS3 and MnPS3-Ce is paramagnetic. The values of the magnetic parameters of MnPS3, such as Ms and Mr, have changed after intercalation with Ce. Optical properties of MnPS3 have been affected due to intercalation with Ce. The quantum calculation indicates a slight narrowing of the energy band gap; this result is in agreement with the small change observed in the optical band gap after intercalation.
