摘要：
The compound Cu 2 Ni 0.75 Co 0.25 SnS 4 (CNCTS) was synthesized using the spin-coating technique. Analysis via Xray diffraction and Raman spectroscopy revealed the formation of a cubic structure at 350 degrees C, with a lattice parameter of 5.40 & Aring; and a crystallite size of 51 A degrees , with no secondary phase detected. Scanning electron microscopy and energy dispersive spectroscopy examination showed that the annealed CNCTS sample at 350 degrees C for 1 h displayed surface morphologies that were nearly uniform, dense, and rough, with a composition close to stoichiometric. UV -Visible -Near infrared analysis indicated that the bandgap energy of the annealed CNCTS at 350 degrees C is 1.39 eV, rendering it highly suitable for low-cost photovoltaic applications.
