“…Trivalent bismuth cation in inorganic compounds or hosts exhibits interesting luminescence properties originating from the excitation and emission of its 6s 2 inert lone pair electrons [121,122]. Bismuth ion (Bi 3+ ) emission spectra show a broadband due to electron transition between the 6s 2 ground states and the 6s6p excited states [123]. The transition between the ground state of Bi 3+ ion ( 1 S 0 ) and its excited triplet levels ( 3 P 0 or 3 P 2 ) [124] is spin forbidden; however, the excited 3 P 1 level undergoes mixing with the singlet 1 P 1 level by spin-orbit coupling, allowing 1 S 0 ↔ 3 P 1 transitions.…”

Scintillator materials convert high-energy radiation into photons in the ultraviolet to visible light region for radiation detection. In this review, advances in X-ray emission dynamics of inorganic scintillators are presented, including inorganic halides (alkali-metal halides, alkaline-earth halides, rare-earth halides, oxy-halides, rare-earth oxyorthosilicates, halide perovskites), oxides (binary oxides, complex oxides, post-transition metal oxides), sulfides, rare-earth doped scintillators, and organic-inorganic hybrid scintillators. The origin of scintillation is strongly correlated to the host material and dopants. Current models are presented describing the scintillation decay lifetime of inorganic materials, with the emphasis on the short-lived scintillation decay component. The whole charge generation and the de-excitation process are analyzed in general, and an essential role of the decay kinetics is the de-excitation process. We highlighted three decay mechanisms in cross luminescence emission, exitonic emission, and dopant-activated emission, respectively. Factors regulating the origin of different luminescence centers controlling the decay process are discussed.

“…The covalent character interaction among the transition metal (TM) 3d-and the carbon (C) 2p-orbitals is the origin of the unusual hardness associated with the TMC. On the other hand, a charge transfer from the TM to the C atoms causes ionic bonds, while the TM states near the Fermi level generate metallic bonds [8,9].…”

Zirconium carbide is a compound widely used in cutting tools, nuclear reactors, field emitter arrays and solar energy receivers; additionally, combined with other materials, it can be used in rocket technology and the aerospace industry. For this work was studied the effect of the high hydrostatic pressure on the electronic, mechanical, vibrational, and optical properties of the ZrC, from first principles calculations based on the Density Functional Theory. The calculated enthalpy and cohesive energy data show a B1 (NaCl) to B2 (CsCl) phase transition at 297 GPa. Besides, results for the calculated equilibrium lattice parameters, bands structure, electron and phonon densities of states, elastic moduli constants, entropy, enthalpy, Gibbs free energy, heat capacity, reflectivity, loss function, conductivity, and dielectric function are consistent with the available experimental and theoretical data. The B1 phase is dynamically stable; in contrast, the B2 phase is not stable. Furthermore, when pressure is applied, the C 2p-orbitals around the Fermi energy contribute significantly to the conduction band, turning ductile the material, with a mixture of metallic and ionic-covalent bonds. On the other hand, ZrC exhibits its highest mechanical resistance, and maximum thermal absorption, above 356° K and 638° K, respectively; but these switch to higher temperatures as pressure is applied. Finally, this compound is a good coating material and a photon detector at low frequencies in the UV region, but also at the visible and infrared regions; although, increasing the pressure, the values of the optical properties increase. The parameters values’ increase of the studied properties, as the pressure increases, indicates that zirconium carbide at high pressures can be used in a greater range of applications more efficiently.
