Abstract
Layered structure MX2 (M = transition metal, X =â¯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 5-15â¯Âµm were obtained on both glass and (110) Si crystalline substrates. The formation mechanism of CrSe2 sub-micro-flakes is suggested.
