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.

“…Inorganic orthophosphate compounds have attracted a great deal of interest in recent years in the phosphor industry for display and solid-state lighting owing to their numerous merits such as good chemical and thermal stability, structural diversity as well as economical and environmentally friendly. The activated phosphates with rare earth or transition metal ion (as an activator) have attracted much attention for their significant applications in solid-state lighting especially in white light-emitting diodes (W-LEDs) and other radiation dosimetry, solid-state laser, display panel applications [1,2]. In general, orthophosphate belongs to the structure of ABPO4, where A represents monovalent cation and B stand for divalent cation, when ionic radii of B is smaller than that of A then ABPO4 shows tridymite structure [3].…”

Because of the importance of inorganic phosphates in the solid-state lighting industry, KZnPO4 doped with some transition metal dopant ions like Cu+ and Ag+ ions were prepared by low-cost co-precipitation method at room temperature followed by annealing at a high temperature around 6500C. The prepared phosphors were characterized by X-ray diffraction. In the case of a Photoluminescence study for KZnPO4 doped with Cu+, the emission was observed at 425 nm, which corresponds to the emission of Cu+ ion. In the case of Ag+ doped KZnPO4, weak emission was observed at 420 nm, which is assigned to the emission of Ag+ ions. CIE chromaticity coordinate of KZnPO4 doped with Cu+ and Ag+ ions phosphor was also evaluated via using OSRAM SYLVANIA color calculator and colour purity of concentration was nearly 95% of Cu+ and Ag+ ions. The obtained outcomes revealed that the prepared phosphor shows potential application in the field of solid-state lighting.

“…These materials have been widely used in various application fields such as in display devices and thermoluminescence dosimeters (TLD), for bio imaging and latent fingerprinting, or in WLEDs, solar cells and scintillators. [ 1–3 ] In the present scenario, lanthanide‐activated phosphors have been widely studied for phosphor‐converted white light emitting diodes (PC‐WLEDs). Blue GaInN chip‐excited YAG:Ce 3+ and Eu 2+ ‐doped SiAlON phosphors have gained popularity as commercial materials for PC‐WLEDs.…”

In the current investigation, a series of NaCa1−xPO4:xDy3+ (x = 0.1, 0.3, 0.5, 0.7, 1.0, 1.5 and 2 mol%) phosphors were synthesized using a solution combustion method and citric acid as fuel. The investigated results from the X‐ray diffraction (XRD) pattern showed phase purity of the synthesized material and orthorhombic crystal structure with space group Pna21. Photoluminescence properties of the synthesized phosphors were investigated. The synthesized Dy3+‐activated phosphor displayed blue (482 nm) and yellow (576 nm) emission under near‐ultraviolet or blue excitations. These emission bands were ascribed due to the 4F9/2→6H15/2 and 4F9/2→6H13/2 transitions of Dy3+ ions. Commission International de l'Eclairage chromaticity coordinates showed emission in the near‐white region for the proposed phosphors under different excitations. In addition, the current–voltage (I–V) characteristics of the NaCa1−xPO4:xDy3+ (x = 1.5 mol%) phosphor‐coated silicon solar cell and an uncoated solar cell were investigated under a solar simulator. The I–V characteristics of the proposed phosphor‐coated silicon solar cell showed enhancement in solar cell efficiency by ~7.92%. The entire studies and their outcomes showed that synthesized phosphors have potential as white light emitting diodes and for solar applications.
