Investigating thermoluminescence properties of Na14Al12Si13O51:Dy3+ phosphor for oxygen ion beam exposure

Abstract The Na14Al12Si13O51: Dy3+ phosphor is synthesized by combustion method and prepared sample was characterized by X-ray Diffraction, SEM, FT-IR and Thermoluminescence (TL) techniques. TL characteristics show the quenching at 3 mol% of Dy3+ ion activated Na14Al12Si13O51: Dy3+ phosphor with single TL glow peak 154 °C at higher temperature. Prepared phosphor material was irradiated oxygen ion beam at different fluences range from 5 × 1010 to 1 × 1014 ions/cm2. Chens peak method and computerized glow curve deconvolutation method was used to evaluate the trapping parameters namely, activation energy, frequency factor, kinetic order associated with the main glow curve in Na14Al12Si13O51: Dy3+ phosphor after irradiation. .
