Abstract

Layered structure MX₂ (M = transition metal, X = S, Se and Te) chalcogenides have rich physic properties and potential applications. While it is still a challenge to prepare the chalcogenides by solvothermal method. In this work, we reported a new solution method to prepare CrSe₂ sub-micro-flakes on different substrates. The surface morphologies, structures and compositions of the precursor CrSe₂(en)_1/2 and CrSe₂ were investigated by SEM, XRD, thermogravimetric, IR and Raman spectra. The CrSe₂ flakes with the sizes of 5–15 µm were obtained on both glass and (110) Si crystalline substrates. The formation mechanism of CrSe₂ sub-micro-flakes is suggested.
