Abstract
Pure and doped (Benzophenone and Urea) triglycine sulphate (TGS) crystals have been grown from aqueous solution by slow cooling method. The influence of doping of benzophenone and urea on the growth and electrical properties have been investigated. The pyroelectric coefficient increases with the addition of benzophenone and urea. It has been observed that the pyroelectric figure of merit of benzophenone doped TGS crystals is less than urea doped crystals. This is attributed to the higher permittivity of benzophenone doped TGS crystals. The Vicker‘s hardness number was found to be increased for doped crystals.
