In this work, high quality TaSe2 single crystals with Different amounts of Pt atoms were grown by a chemical vapor transport method. The Powder and single crystal X-ray diffraction were conducted to investigate the phase purity and structural characterization of as grown samples. The results using Rietveld analysis in conventional as well as quantum transfer Q parameter modes confirmed the 2H-TaSe2 in all samples with constantly increased of a and c unit cell parameters. This is firm evidence that the Pt atoms are intercalated in the host compounds successfully rather than being substituted by the Ta atoms in the crystalline structure. Thus, the dominant intercalation by occupying the tetrahedral and octahedral sites between the TaSe2 slabs will fill the van der wall gaps which further generate disorder in the lattice. This is a promising scenario to enhance electronic features of the 2H-TaSe2 single crystals.
