The optical absorption spectrum of Co 2+ ions doped in zinc thallium sulphate hexahydrate has been studied at room and liquid nitrogen temperatures. The crystal shows characteristic absorption of Co ~-~ ion in the visible and near infrared regions. The observed bands are assigned as transitions from
