The Cu2Zn1-xCrxSnS4 (x=0- 1) compound was synthesized by sol-gel method in order to modulate the structural and morphological characteristics of the compound. XRD studies revealed that there is small variation of lattice constants with slight distortion in crystal structure due to partial substitution (Cr) which confirms the successful entrance of Cr2+ ions into the Cu2ZnSnS4 lattice. While Raman confirmed the formation of a pure Cu2ZnSnS4 phase with slight peak shifting due to the substitution, FESEM images demonstrated that the particle size ranged in the nanoscale with a regular surface distribution. Photoluminescence measurements indicate that increasing chromium content causes changes in the optical bandgap, potentially leading to modifications in the optical properties. Meanwhile, magnetic analysis confirms that increasing chromium content directly affects the magnetic properties of the compound, causing it to shift from paramagnetic to weakly magnetic behaviour. The results show that the optical and magnetic properties of the Cu2ZnSnS4 compound can be changed by replacing zinc with chromium, which enhances its use in photocatalysis and thin-film solar cells.
