Characterization of luminescent and magnetic properties. a Unnormalized PL spectra of pristine monolayer MoS2, Co–MoS2, and (Co, Cr)-MoS2. The inset shows the normalized PL spectra. b Analysis of the PL spectral shapes and PL intensity mappings, and c Magnetization vs magnetic field (M-H) curves. d Temperature-dependence of magnetization (M–T) curves of (Co,Cr)-MoS2 with FC and ZFC process
