	abstract = {The mixed crystals of the Tutton{\textquoteright}s salt doped with Li following the empirical formula K2LiyNixCo1-x (SO4)2.6H2O, were synthesized from the slow evaporation of the solvent at constant temperature. The presence of K, S, Ni, Co and O elements in the studied crystalline structure was confirmed by EDS spectroscopy using a scanning electron microscope and their quantification including Li was carried out with the help of ICP-OES technique. Raman spectroscopy in the range 100-3600 cm-1, confirmed the presence of tetrahedral (SO4), octahedral complexes Ni(H2O)6, Co(H2O)6, and H2O molecules in the crystal structure. Our UV{\textendash}vis studies have shown that the mixed crystals have good optical transparency in the ultraviolet (200-350 nm) and infrared (750-1000 nm) region. The direct and indirect optical energy gap of the synthesized crystals were determined from the Tauc{\textquoteright}s plot. XRD diffractograms of the sample crystals do not show any specific changes due to the presence of Li ion in the crystalline network.},
