“…In particular, A=K materials with divalent cations (Zn, Pd, Cd, Sr) were characterized [1][2][3][4]. These and other related diphosphates have awaked great interest in relation to their potential technological applications, as some of them may have magnetic and useful catalytic properties [5][6][7].…”

The pyrophosphate K 2 NiP 2 O 7 has been synthesized by the classic ceramic method and characterized by Xray diffraction, solid-state 31 P magic angle spinning (MAS) NMR, and IR and electrical impedance spectroscopy. The solid-state 31 P MAS NMR, performed at 121.49 MHz, shows two isotropic resonances at −17.66 and −19.94 ppm, revealing the existence of two phosphorus environments in the structure. The electrical conductivity and dielectric properties have been investigated in the frequency and the temperature range of 200 Hz-1 MHz and 603-728 K, respectively. The frequency dependence of the conductivity is interpreted using the augmented Jonscher relation. The close values of activation energies obtained from the analysis of hopping frequency and dc conductivity imply that the transport is through ion hopping mechanism. The charge carrier concentration in the investigated sample has been evaluated using the Almond-West formalism and shown to be independent of temperature. Thermodynamic parameters such as the free energy of activation ΔF, the enthalpy ΔH , and the change in entropy ΔS have been calculated.

The use of phosphate‐based thermoluminescence dosimeter (TLD) materials in current scenarios is presented here, particularly for the field of low dosimetry. TLD materials are currently researched for their use in for example environmental dosimetry, personal dosimetry, and medical dosimetry. There are several TLD materials available such as: sulphates, borates, fluorides, and sulphides, including some metal oxides and perovskites, which are the most used and have been widely explored. In the present scenario, new interest is being focused on the need for thermoluminescent materials for application in material science and radiation dosimetry for low‐dose dosimetry. These doped TLDs are prepared using different techniques including solid‐state reaction methods, combustion methods, wet chemical methods, and sol gel methods. Therefore, among the above stated TLDs, phosphates have opened a new door in radiation dosimetry, particularly in low‐dose dosimetry over the last few years. This paper mainly deals with a review of various phosphate‐based TLD materials and recent advancements in phosphates for TL dosimetry.
