“…As a result, the trapping parameters of a thermoluminescent material are the foundation for an accurate dosimetry investigation. [54][55][56][57][58][59][60][61] Here, the information about the trap level obtained from the kinetic parameters (Table 9) shows that almost one electron is trapped there because of the value of (shape factor) 0.435 and it shows the general order kinetics (b) and the needed energy to escape one electron from the trap level is high (0.50-0.86 eV), i.e. activation energy (E), which shows the formation of traps is high and stable.…”

Here, the synthesis and luminescence analysis of the Tb3+‐activated phosphor were reported. The CaY2O4 phosphors were synthesized using a modified solid‐state reaction method with a variable doping concentration of Tb3+ ion (0.1–2.5 mol%). As synthesized, the phosphor was characterized using Fourier transform infrared spectroscopy (FTIR) and X‐ray diffraction analysis techniques for the optimized concentration of doping ions. The prepared phosphor showed a cubic structure, and FTIR analysis confirmed functional group analysis. It was discovered that the intensity of 1.5 mol% was higher than at other concentrations after the photoluminescence (PL) excitation and emission spectra were recorded for different concentrations of doping ions. The excitation was monitored at 542 nm, and the emission was monitored at 237 nm. At 237 nm excitation, the emission peaks were found at 620 nm (5D4→7F3), 582 nm (5D4→7F4), 542 nm (5D4→7F5), and 484 nm (5D4→7F6). The 1931 CIE (x, y) chromaticity coordinates showed the distribution of the spectral region calculated from the PL emission spectra. The values of (x = 0.34 and y = 0.60) were very close to dark green emission. Therefore, the produced phosphor would be very useful for light‐emitting diode (green component) applications. Thermoluminescence glow curve analysis for various concentrations of doping ions and various ultraviolet (UV) exposure times was carried out, and a single broad peak was found at 252°C. The computerized glow curve deconvolution method was used to obtain the related kinetic parameters. The prepared phosphor exhibited an excellent response to UV dose and could be useful for UV ray dosimetry.
