The present paper reports the experimental results of dysprosium doped calcium sulphate (CaSO4:Dy) films deposited by spray pyrolysis method. CaSO4:Dy films were deposited on three different surfaces: glass, aluminum and quartz substrates at temperatures in the range from 450 to 600 °C. Structural and morphological characteristics of CaSO4:Dy films were observed. Thermoluminescent characteristics of films were determined by irradiating ultraviolet energy region. Thermoluminescent glow curve of CaSO4:Dy films with glass and aluminum substrates showed a peak under environmental irradiation. Both TL response glow shape and intensity of CaSO4:Dy films UV irradiated as a function of substrates were studied.
► We carried out the preparation of calcium sulfate films doped with dysprosium (CaSO4:Dy) by spray paralysis method. ► SEM and EDS techniques were applied to study the surface topography and chemical composition of the CaSO4:Dy films. ► Thermoluminescent characteristics of films were determined by irradiating ultraviolet energy region. ► The thermoluminescent response of CaSO4:Dy films as a function of substrate was analyzed.
