Thermoluminescence (TL), as an experimental technique, finds application in diverse scientific disciplines such as radiation dosimetry, archaeology, geology, medicine, solid state physics, biology and organic chemistry.
CaF2: Mn had major impact in this field due to its excellent sensitivity and simple glow curve structure.
Defects in the lattice structure are responsible for these traps.
However, the water present in the product is associated with the rigid network of the structure, not a lose molecule.

Fig. 1 (a) Band structure of a pure crystal, (b) Irradiation and charge trapping, and (c) charge de-trapping and recombination A simple model having one trap and one recombination center explains luminescence, however many important properties cannot be explained by this simple model.
The structure of feldspar is complex and comprises a number of substitutional impurities such as Ba, B, Cs, Ga, Fe, Li, Mg, Mn REE, Sn, Sr, etc. that substitute for K, Na, Ca, Al, Si, O [7, 19-22].

Also, the structure indicated that some particles are refined while some appeared spherical.
However, aggregate, and clustered structures were observed and no possible fracture across the coating substrate was noticed.
The result showed that the structure is characterized by amorphous nature with several diffraction peaks Mn(Zn), Fe(Mn) and Fe(Zn Ca) etc.
This wide range in hardness could be due to elements including coating microstructure, residual stress level, porosity, phase structure, binder content, and particle size.

(xi) The ML provides unique source of information on the electronic structure of dislocations in alkali halide crystals.
It is of worth to mention that, unlike in semiconductors in which the electronic structure of the dislocations has been studied by different methods [113-115], there has been practically least investigation of the dislocation structure in AHCs.

Others employed pre-trained molecule and protein models in an interpretable nested graph neural network [28], or a meta path-aggregated heterogeneous graph neural network to capture complex structures and rich semantics in biological heterogeneous graphs [29].
