“…Slight shifts of the POP bridges stretching vibration bands in the b-phase spectrum (S2, S3, and S5) in relation to that of the a-form (S4 and S6) are due to the structural differences between the hightemperature orthorhombic and the lowtemperature monoclinic phase. A similar effect was observed and described in the works [13,20].…”

“…In the diffraction patterns of the samples S2, S3 and S5 reflections characteristic of the b-KErP 2 O 7 monoclinic structure (PDF 00-049-0766) are visible, whereas XRD patterns of the samples S4 and S6 are characteristic of the orthorhombic a-KErP 2 O 7 structure (PDF 00-049-0767). Figure 2 presents [12,13,20]. In the spectra of KErP 2 O 7 (S2-S6) the range of the bands occurrence is the same as in the works [12,13,20], which confirms purity of the obtained products.…”

“…For the last few decades, double diphosphates of a general formula M I LnP 2 O 7 (M I = Li, Na, K, Rb, Cs, Tl, Ag; M III = Al, Ga, In, Fe, Sc, Y, Ln, transition metal) have attracted considerable interest [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. It has been primarily focused on the crystal structure, synthesis methods and prospective practical applications.…”

The phase equilibria occurring in the ErPO 4 -KPO 3 system were investigated by thermoanalytical, X-ray powder diffraction and FTIR methods. On the basis of the obtained results, its phase diagram was proposed. This system includes one intermediate compound, KErP 2 O 7 . This phosphate decomposes peritectically at about 1025°C and occurs in two polymorphic forms; transformation b/a-KErP 2 O 7 proceeds at about 358°C. The binary erbium end potassium diphosphate, KErP 2 O 7 , was obtained by the ceramic and modified Pechini methods. Structural properties were characterized by X-ray powder diffraction and FTIR spectroscopy.Keywords Phase diagram Á Erbium and potassium diphosphate Á DSC Á DTA/TG/DTG Á XRD

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.
