Facile synthesis and thermoluminescence properties of nano bio-ceramic β-Ca(2)P(2)O(7):Dy phosphor irradiated with 75 meV C(6+) ion beam

Dy(3+) doped β-Ca(2)P(2)O(7) phosphor has been synthesized using wet chemical method. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis confirmed the formation of β-Ca(2)P(2)O(7):Dy nano-phosphors. However, photoluminescence (PL) study was carried out to confirm the presence of dopant ion in the host matrix of β-Ca(2)P(2)O(7):Dy material. Thermoluminescence (TL) glow curves of β-Ca(2)P(2)O(7) were recorded for different concentrations of Dy(3+) after exposure to various fluences of C(6+) ion beam (75 meV). TL sensitivity of β-Ca(2)P(2)O(7):Dy(3+) (0.1 mol%) phosphor was 3.79 times more than commercially available CaSO(4):Dy(3+). 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-Ca(2)P(2)O(7) nanoparticles along with high stability of TL glow curve makes this nanomaterial a good candidate for C(6+) ion beam dosimetry.
