ABSTRACT = {Experimental preparation of graphene like 2D silicon is a great challenge due to the dominant sp<sup>3</sup> hybridization in silicon. We have synthesized quasi 2D crystalline silicon nanosheets by topochemical exfoliation of layered Zintl phases, which bear signatures of properties predicted theoretically. Quasi-two-dimensional silicon nanosheets were uniformly dispersed within a conducting polyaniline matrix to fabricate solid-state nanocomposites with varying silicon loadings. The resulting polyaniline–quasi-2D silicon composites were systematically examined for their structural characteristics and optical emission behavior. Notably, the nanocomposites exhibit intense photoluminescence at room temperature, with an emission efficiency significantly higher than that of pristine quasi-2D silicon. The functional characteristics of the nanocomposite can be tailored by adjusting the loading and spatial dispersion of the nanoscale components, the nature of the host matrix, and the interfacial interactions between them. This nanocomposite is a promising candidate for the development of efficient thermoelectric material and has huge potential for applications in electronics and sensing.},
