“…(7) Zambare and Murthy used the solid-state reaction method to investigate the properties of Eu-doped YPVO 4 , Y 2 O 3 , and YLaVO 4 phosphors. (8) They used 254-nm-wavelength irradiation to excite the photoluminescence emission spectra of YPVO 4 :Eu 3+ (0.5%), which displayed photoluminescence (PL) emissions at 365, 540, 561, 594, and 611 nm, and Y 2 O 3 :Eu 3+ (0.5%), which displayed PL emissions at 536, 583, 589, 594, 600, 615, and 632 nm.…”

In this study, the raw materials of BaCO 3 and ZrO 2 powders with different average diameters were used to prepare BaZrO 3 :Eu 0.025 phosphors by the solid-state reaction method. The raw materials with different average diameters were prepared by mixing them by the ball milling method and/or grinding them in a nanoscale grinding machine. As different grinding processes were used, the BaCO 3 and ZrO 2 powders had the average diameters of 2124, 707, 645, and 496 nm. When raw materials with the average diameter of 2124 nm were used and the calcination temperature was changed from 1100 to 1400 °C, the BaZrO 3 :Eu 0.025 phosphors showed two strong orange emission bands with peaks at the wavelengths of 574 and 596 nm and two weak emission bands with peaks at 620 and 650 nm. The maximum intensity of the emission spectrum of the BaZrO 3 :Eu 0.025 phosphors increased with increasing calcination temperature. When the raw materials with the average particle sizes of 707, 645, and 496 nm were used and the calcination temperature was changed from 950 to 1150 °C, the BaZrO 3 :Eu 0.025 phosphors showed one broad blue emission band with central wavelengths located at 464-466 nm. In this study, we prove that when the sizes of the source materials are different, the luminescence properties of the BaZrO 3 :Eu 0.025 phosphors will have large variations after they are calcined at different temperatures.

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.
