Enhancement in ferroelectric, pyroelectric and photoluminescence properties in dye doped TGS crystals

► Amaranth dye doping in TGS crystals resulted in hourglass morphology. ► Doping resulted in enhancement of Curie temperature from 49 to 53 °C. ► Low cut off (230 nm) and wider transmittance window observed. ► Strong hyper-luminescent emission bands at 350 and 375 nm were observed. ► High and uniform figure of merit in ferroelectric phase was obtained
