“…183 A series of Ba 2 Mg(PO 4 ) 2 :Eu 3+ phosphors were reported utilizing a wet chemical method. 184 At 396 nm, the strongest excitation peak was observed in the spectra, and two representative emission peaks were found in the emission spectra; one at 592 nm (MD transition) and the other one at 615 nm (ED transition). High color purity of the phosphors was observed with the CIE color coordinates (0.586, 0.412) at 592 nm, and that at 615 nm was found to be (0.680, 0.319).…”

The CaAlBO4:RE (RE = Dy3+, Eu3+, Sm3+) phosphor were prepared via combustion synthesis and studied by X‐ray diffraction (XRD), Fourier‐transform infrared (FTIR) analysis, scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy (EDS), photoluminescence (PL) spectra and CIE coordinates. The phase formation of the obtained phosphor was analyzed by XRD and the result was confirmed by standard PDF Card No. 1539083. XRD data successfully indicated pure phase of CaAlBO4 phosphor. The crystal structure of CaAlBO4 phosphor is orthorhombic with space group Ccc2 (37). The SEM image of CaAlBO4 phosphor reveals an agglomerated morphology and non‐uniform particle size. The EDS image provides evidence of the elements present and the chemical makeup of the materials. Under the 350 nm excitation, the emission spectrum of Dy3+ activated CaAlBO4 phosphor consists of two main groups of characteristic peaks located at 484 and 577 nm which are ascribed to 4F9/2 → 6H15/2 and 4F9/2 → 6H13/2 transition of Dy3+ respectively. The PL emission spectra of CaAlBO4:Eu3+ phosphor shows characteristics bands observed around 591 and 613 nm, which corresponds to 5D0 → 7F1 and 5D0 → 7F2 transition of Eu3+ respectively, upon 395 nm excitation wavelength. The emission spectra of Sm3+ activated CaAlBO4 phosphor shows three characteristic bands observed at 565, 601 and 648 nm which emits yellow, orange and red color. The prominent emission peak at the wavelength 601 nm, which is attributed to 4G5/2 → 6H7/2 transition, displays an orange emission. The CIE color coordinates of CaAlBO4:RE (RE = Dy3+, Eu3+, Sm3+) phosphor are calculated to be (0.631, 0.368), (0.674, 0.325) and (0.073, 0.185). As per the obtained results, CaAlBO4:RE (RE = Dy3+, Eu3+, Sm3+) phosphor may be applicable in eco‐friendly lightning technology.

“…Phosphate phosphors are also prepared by wet chemical method. [ 32–35 ] In wet chemical methods, chemical reactions take place among the precursors in a solution under proper experimental conditions. In this method, starting materials are dissolved in a solvent such as distilled water, a clear solution is obtained, then heated, and finally the desired compound is obtained in powder form.…”

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.
