Low-dimensional materials have attracted much interest due to their enhanced or modified optical, electronic and mechanical properties compared to those of bulk materials. A nanosheet bundle is also one of the potential structures for technological applications. The Si-based nanosheet bundles have been synthesized from CaSi₂ microwalls on Si substrates. The structural properties of the bundles were characterized in the past. In this study, the photoluminescence (PL) property of the bundles is characterized, and the results are discussed in terms of quantum effect and surface states of the nanosheets.
