Abstract

Dy³⁺ doped β-Ca₂P₂O₇ phosphor has been synthesized using wet chemical method. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis confirmed the formation of β-Ca₂P₂O₇:Dy nano-phosphors. However, photoluminescence (PL) study was carried out to confirm the presence of dopant ion in the host matrix of β-Ca₂P₂O₇:Dy material. Thermoluminescence (TL) glow curves of β-Ca₂P₂O₇ were recorded for different concentrations of Dy³⁺ after exposure to various fluences of C⁶⁺ ion beam (75 meV). TL sensitivity of β-Ca₂P₂O₇:Dy³⁺ (0.1 mol%) phosphor was 3.79 times more than commercially available CaSO₄:Dy³⁺. TRIM code based on the Monte Carlo simulation was used to calculate the absorbed doses, ion range and main energy loss. Glow curve de-convolution (GCD) method was used to determine the number of TL peaks and their trapping parameters. The wide linear response of β-Ca₂P₂O₇ nanoparticles along with high stability of TL glow curve makes this nanomaterial a good candidate for C⁶⁺ ion beam dosimetry.
