“…Similar characteristics of Infrared spectra observed only for EuAl3(BO3)4 [69] but not for other ReM3(BO3)4 [34,63,[66][67][68]. In case of Sm 3+ doped YAl3(BO3)4 several bands have been found at 869, 918 and 1064 cm −1 but X-ray diffraction diffractograms do not contain reflexes related to monoclinic phases [71].…”

The crystal structure of YAl3(BO3)4 is obtained by Rietveld refinement analysis in the present study. The dynamical properties are studied both theoretically and experimentally. The experimental Raman and Infrared spectra are interpreted using the results of ab initio calculations within density functional theory. The phonon band gap in the Infrared spectrum is observed in both trigonal and hypothetical monoclinic structures of YAl3(BO3)4. The electronic band structure is studied theoretically, and the value of the band gap is obtained. It was found that the YAl3(BO3)4 is an indirect band gap dielectric material.

A series of SrAlBO4: Eu phosphors doped with different concentrations of Eu (0.1 0.3, 0.5, 0.7, 1.0 mol%) have been synthesized via solid state diffusion method and their thermoluminescence properties were analyzed for gamma and carbon ion irradiation. The phase purity, morphological properties, vibrational features and thermal stability of the prepared sample were analyzed by X‐Ray diffraction (XRD) and scanning electron microscope (SEM), Fourier transform infrared (FT‐IR) and Thermogravimetric/Differential Thermal Analyzer (TG/DTA) techniques, respectively. The TL properties of the proposed materials shows broad dosimetric bands, peaking at 202 oC for 0.12 kGy gamma irradiation. The highest TL intensity has obtained for 0.7 mol% concentration of Eu ions under Gamma irradiation. Furthermore, the glow curve of the proposed materials shows a broad emission band, centered at 148 °C under carbon ion beam irradiation and exhibits the highest emission intensity for 0.1 mol% Eu concentration. In addition, the dosimetric trapping parameters of the prepared samples such as symmetry factor, order of kinetics, activation energy, frequency factor have been analyzed using various methods such as chen’s peak shape method, initial growth method, Ilich method. The obtained results of the samples show the potential for dosimetric application.
