WebHowever, conventional thermal-NIL that uses polymeric resin such as Poly(methyl methacrylate) has limited applicability to the fabrication of optical devices, owing to the low refractive index of the resin. As such, we developed SnO2-nanoparticle-containing imprint resin that has a high refractive index and is applicable in the thermal-NIL method.
