“…shows the TL response curve of the CaNa 2 (SO 4 ) 2 :Dy nanophosphor for a wide range of gamma doses from 10 Gy to 30 kGy and the synthesized material exhibited a linear response for the range 10 Gy to 10 kGy. Therefore, this nanophosphor is useful for radiation therapy within the range 10 Gy to 80 Gy and in high radiation dosimetry for accidental and reactor areas with doses greater than 1 kGy …”

Thermoluminescence (TL) materials exhibit a wide range of applications in different areas such as personal dosimetry, environmental dosimetry, medical research etc.Doping of different rare earth impurities in different hosts is responsible for changing the properties of materials useful for various applications in different fields. These materials can be irradiated by different types of beams such as γ-rays, X-rays, electrons, neutrons etc. Various radiation regimes, as well as their dose-response range, play an important role in thermoluminescence dosimetry. Several TL materials, such as glass, microcrystalline, nanostructured inorganic materials and recently developed materials, are reviewed and described in this article.

Green‐light emission through energy transfer from Ce³⁺ to Tb³⁺ ions in the Li₂SO₄–Al₂(SO₄)₃ system

An energy transfer process from Ce3+ to Tb3+ ions was successfully achieved in a Li2SO4–Al2(SO4)3 mixed‐sulphate system. A wet‐chemical synthesis was employed to prepare the Li2SO4–Al2(SO4)3 system by doping Ce3+ and Tb3+ ions individually as well as collectively. The phases were identified using X‐ray diffraction studies. The as‐prepared samples were characterized by FT‐IR and photoluminescence measurements. Green‐light emission was exhibited by Ce3+, Tb3+ co‐doped Li2SO4–Al2(SO4)3 system, thus, indicating its potential as a material for display devices or in the lamp industry.

A Eu3+‐activated Ca7Mg2(PO4)6 phosphor was prepared at high temperature (800°C) using a solid‐state reaction method. The crystal structure, phase formation of the prepared phosphor was characterized using X‐ray diffraction patterns and Fourier transformed infrared analysis. The luminescence properties of the synthesized phosphor were characterized using photoluminescence and thermoluminescence techniques. The prepared phosphor showed two emission peaks at 594 nm with an orange colour due to the 5D0→7F1 transition and at 612 nm a red colour due to the 5D0→7F2 transition under 396 nm near‐UV excitation. The prepared phosphors were irradiated with different doses of γ‐rays from a 60Co gamma irradiation source. Thermoluminescence glow curves for this sample phosphor were obtained using a Nucleonix 1009I TL reader. Synthesized phosphor samples were exposed to a 3.6 kGy dose of γ‐rays. The thermoluminescence glow curve of the Ca7Mg2(PO4)6:0.05 mol%Eu3+ phosphor showed maximum intensity at all concentrations of Eu3+ ions. The Ca7Mg2(PO4)6:0.05 mol%Eu3+ phosphor was irradiated with different doses of 60Co γ‐irradiation and a linear response was observed between 0.6 kGy and 3.6 kGy. Trapping parameters such as activation energy, frequency factor and order of kinetics were calculated. The CIE chromaticity diagram showed the colour coordinates of the synthesized phosphor in the orange and red regions of the visible spectrum; this spectral feature revealed high colour purity and excellent chromaticity coordinate characteristics. Photoluminescence and thermoluminescence properties revealed that the prepared phosphor could be a potential red‐emitting phosphor for eco‐friendly white light generation and an excellent thermoluminescent dosimeter material for thermoluminescence dosimetric applications.
