Two-dimensional single- and/or multi-layered Mica (cas 12001-26-2) exfoliated from original bulk mica are fabricated via a simple sonication technique. At 298 K, the photoluminescence spectra of nano-sized mica reveal green emission in the region of approximately 516 nm, while the spectra of bulk mica do not exhibit photoluminescence characteristics. However, at 70 K, it is observed that both nano-sized and bulk mica have slightly similar photoluminescence emission characteristics. Here, in contrast to the conventional energy bandgap generally increasing at the nano-size, muscovite-type mica exhibits a phenomenon in which the energy bandgap becomes narrower as a mono-layer develops owing to frequent lattice relaxations.
