sulfate (KAS) at different pH. The well-defined single KAS crystals have been grown at pH 3,
5 and 7 engaging the slow evaporation process. Crystal structure and lattice parameters of
grown KAS crystals have been determined using the powder X-ray diffraction technique. The
impact of pH on optical transparency of KAS crystal is studied within 200–1000 nm through
UV–visible optical analysis. He-Ne laser assisted Z-scan method is used to analyse third …
