Li3PO4: M (M=Tb, Cu) phosphors for radiation dosimetry

Li3PO4: M (M=Tb, Cu) phosphors for radiation dosimetry The dosimetric phosphors Li3PO4:M (M = Tb, Cu) were produced by modified solid-state method. The structural and morphological characterization was carried out through X-ray diffraction (XRD) and scanning electron microscope (SEM). Additionally, the photoluminescence (PL), thermoluminescence (TL) and optically stimulated luminescence (OSL) properties of powder Li3PO4 doped with Tb and Cu were studied. It is advocated that Li3PO4: Cu phosphor not only shows higher OSL sensitivity (25 times or more) but also gives faster decay in OSL signals than that of Li3PO4: Tb3+ phosphor. The minimum detectable dose (MDD) of Li3PO4:M (M = Tb, Cu) phosphors is found to be 21.69 × 10−3 and 3.33 × 10−6 J⋅kg−1, respectively. In OSL mode, phosphor shows linear dose response in the range of 0.02–20.00 J·kg−1. In TL mode, sensitivity of Li3PO4: Cu phosphor is more than that of Li3PO4: Tb phosphor. The kinetics parameters such as activation energy and frequency factors were determined by peak shape method, and photoionization cross sections of prepared phosphor were calculated. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Rare Metals Springer Journals

Abstract

The dosimetric phosphors Li3PO4:M (M = Tb, Cu) were produced by modified solid-state method. The structural and morphological characterization was carried out through X-ray diffraction (XRD) and scanning electron microscope (SEM). Additionally, the photoluminescence (PL), thermoluminescence (TL) and optically stimulated luminescence (OSL) properties of powder Li3PO4 doped with Tb and Cu were studied. It is advocated that Li3PO4: Cu phosphor not only shows higher OSL sensitivity (25 times or more) but also gives faster decay in OSL signals than that of Li3PO4: Tb3+ phosphor. The minimum detectable dose (MDD) of Li3PO4:M (M = Tb, Cu) phosphors is found to be 21.69 × 10−3 and 3.33 × 10−6 J⋅kg−1, respectively. In OSL mode, phosphor shows linear dose response in the range of 0.02–20.00 J·kg−1. In TL mode, sensitivity of Li3PO4: Cu phosphor is more than that of Li3PO4: Tb phosphor. The kinetics parameters such as activation energy and frequency factors were determined by peak shape method, and photoionization cross sections of prepared phosphor were calculated.
