ZincSulfateHeptahydrate, a novel inorganic optical material has been synthesized and crystals were grown from aqueous solution employing the technique of controlled evaporation. The various functional groups of the sample were identified by Fourier transform infra–red spectroscopic analysis. UV visible studies reveal that ZincSulfateHeptahydrate has UV cutoff wavelength at 200nm. Dielectric studies show that dielectric constant and dielectric loss decreases with increasing frequency and finally it becomes almost a constant at higher frequencies for all temperatures.Mechanical stability on the title crystal was carried out to propose the material for useful applications.
