Dosimetry is a technique that quantitatively measures the ionizing radiation absorbed by matter. The present study was conducted on the barites from a mine at Dongargaon in Central India. Morphological and structural analysis of proposed sample was carried out using X‐ray diffraction and standard error of the mean. Thermal analysis and chemical composition of the proposed sample were carried out using thermogravimetric analysis and differential thermal analysis, and electron probe microanalysis. Thermoluminescence (TL) studies on a natural barite sample were performed using a Nucleonix TL1009I TL reader following sample irradiation with γ‐rays generated from a 60Co irradiation source. A broad TL glow curve was observed after TL study that was then deconvoluted using TLanal deconvolution software. Trapping parameters from the sample such as activation energy (E), order of kinetics (b), and frequency factor (s) were calculated using Chen’s peak shape method, the initial rise method, and Ilich’s method. The results indicated that the natural barite sample could be used in high‐dose TL dosimetric applications in various fields.

“…Excitation of LLPs is mostly done with the help of UV or visible light, but sometimes the use of ionizing radiation, such as X-rays, etc., can be done for PerLum nanomaterials with a lower value of bandgap energy. Research has found that the use of optical excitation and ionizing radiation gives rise to the filling of different traps [ 320 , 321 ]. This phenomenon has a simple explanation: optical charging takes place via the direct excitation of an activator, while charging via ionizing radiation is assisted by the avalanche effect generated by charge carriers.…”

“…Rare earth (RE) doped materials are often being investigated as it is suitable for photonic applications [1,2] such as amplifiers, lasers, displays and optical telecommunication [3][4][5]. Materials doped with rare earth ions are promising due to their thermal and chemical stability as well as distinct luminescence characteristics [6][7][8].…”

“…Materials doped with rare earth ions are promising due to their thermal and chemical stability as well as distinct luminescence characteristics [6][7][8]. Among RE ions, erbium (Er 3+ ) has gotten much interest because of its favourable energy level structure and up-conversion luminescent characteristics with multiple emissions in both infrared and visible regions [2,4,5,9,10]. Silica (SiO 2 ) glass is an excellent host for RE ions owing to its good chemical stability, thermal resistance, high transparency and inexpensive [11].…”

Er3+ has been gaining much interest due to the multiple emissions in both infrared and visible regions. Based on the previous study, SiO2-TiO2 have been proven to be an excellent host for Er3+. However, Er3+ exhibits a low absorption cross-section when doped into the silica-based host. Therefore, Yb3+ has been introduced into the matrix and acts as a sensitiser to increase the luminescence intensity. Er3+/Yb3+ co-doped 75SiO2-25TiO2 nanofiber with different Er3+/Yb3+ ratios were fabricated via the sol-gel electrospinning method. The FESEM result shows the diameter of the nanofibers in the range of 62 to 515 nm. The absence of any peak within the 3000-4000 cm-1 range in the FTIR spectra indicates the complete removal of the OH group. The XRD results imply that all samples were amorphous. The PL spectra showed strong green emission peaks, which were ascribed to 2H11/2 → 4I15/2 as well as red emission peaks attributed to 4F9/2 → 4I15/2 Er3+ transitions. The PL intensity was varied according to the Yb3+ concentration. The addition of Yb3+ was proven to aid the increment of PL intensity. Nevertheless, the PL intensity reduced when too high of Yb3+ concentration was used due to the concentration quenching effect.
