Cathodoluminescence and green-thermoluminescence response of CaSO4:Dy,P films

► The CaSO4:Dy,P films were prepared by using the ultrasonic spray pyrolysis method. ► Luminescence spectra of the CaSO4:Dy,P films display the emission bands of the ions (SO4)2− and Dy3+. ► The CaSO4:Dy,P films were irradiated with a 90Sr/90Y beta source. ► The TL intensity of the films depends on the temperature of deposit.
