Abstract

• Crystals of K+ (1mol%) doped Lithium Ammonium Sulphate, LiNH4SO4, were grown by slow evaporation method of room temperature. Starting materials of Lithium Sulphate, Li2SO4 and Ammonium Sulphate, (NH4)2SO4 with the addition of (1mol%). Potassium Sulphate K2SO4 were used to grow and synthesis the crystals. Structural investigation of the crystal will be reported by XRD method. Lattice parameters of the crystal were also examined. FTIR transmission spectrum of the crystal will be collected by pc controlled FTIR-8400 /SHIMADZU spectrometer between the wavenumber range of 400 cm-1 and 4000 cm-1 region.
