We theoretically study the light-induced Floquet states of phosphorene nanoribbon and their influences on spin transport.We find that phosphorene nanoribbon opens new energy gaps and the conductivities are suppressed under circularly polarized light.The introduction of ferromagnetic substrates will induce splitting in both bulk and quasi-flat bands.Fermi energy can be used to tune the spin polarization.These phenomena pave the way to optical control of spin transport of two-dimensional materials such as phosphorene.
