A gradient refractive-index (GRIN) plastic rod comprises a monomer, a surfactant monomer (surfmer), and nanoparticles. The surfmer, which keeps nanoparticles and polymers in a good mutual solubility, can increase a content of nanoparticles, and thus overcome a problem of the resulting opaque plastic rod caused by introducing nanoparticles in the prior art. Moreover, nanoparticles can increase a difference of refractive index, the numerical aperture and a transmission efficiency of the GRIN plastic rod.
