The group of III–VI (III: Ga, III–VI: S,Se) layered compounds, with large structural anisotropy, seems to be a promising family of materials suitable for intercalation applications, mainly as electrodes in solid state batteries [1]. Each layer consists of four two-dimensional sheets of like atoms in the sequence X-M-M-X with mainly strong covalent bonding between the sheets, while the complete four fold layers are bound together by weak Van der Waals type forces, forming different crystalline structures (polytypes) with different stacking sequences [2]. Among other intercalants it is Li on which attention has been centered [3,4], although the question has been asked whether these compounds are really intercalated or whether new compounds with Li participation are formed [5]. In this paper is presented a new damageless method for the characterization of intercalated samples by studying the influence of the intercalant on the free exciton (FE) line of the host material.
