Unveiling the Potential of Sm3+ Doped Li2SrSiO4 Phosphor for UVC Dosimetry: Comprehensive Analysis with Synthesis, Morphological, Elemental and Thermoluminescence Studies

“…Such defects get located in the band gap and can drastically change the luminescence characteristics of materials by trapping charge carriers in localized energy levels. 2 Hence, by evaluating the kinetic parameters of the lattice using TL, the formation of electronic trap levels caused by dopant ions can be studied. Applications of TL include radiation dosimetry in the environment, medical diagnostics, radiology, cosmic radiation detection, bone dosimetry, toxicity studies, aeroplane safety, accidental dosimetry and personal dosimetric monitoring.…”

“…The emission is exhibited due to structural defects brought on by doping in the host lattice. Such defects get located in the band gap and can drastically change the luminescence characteristics of materials by trapping charge carriers in localized energy levels . Hence, by evaluating the kinetic parameters of the lattice using TL, the formation of electronic trap levels caused by dopant ions can be studied.…”

“…For UVC dosimetry, a lot of inorganic silicate based phosphors are researched because a silicate-based compound offers highly stable thermal properties, excellent homogeneity, high melting point (∼1700 °C) because of the silicon–oxygen covalent bonds throughout the crystal structure, and a large band gap due to being an insulator and being insoluble in water and other organic solvents. All these properties make it potentially suitable for optoelectronic, laser, and other high-tech applications. , There are various types of rare earth (RE) doped/undoped silicate phosphors including Bi 4 Si 3 O 12 :Dy 3+ , Li 2 SiO 3 , Mg 2 SiO 4 :Eu 3+ , lead-silicate glasses (PbO-SiO 2 ), Lu 2 SiO 5 :Pr 3+ , SrZrSi 2 O 7 :Ce 3+ , Sr 3 MgSi 2 O 8 : Eu 2+ ,Dy 3+ ,Mn 2+ , CaBaSiO 4 :Dy 3+ , Ba 5 Si 8 O 21 :Eu 2+ , Dy 3+ , and Cd 0.95 Eu 0.05 SiO 3 that are being successfully researched. When it comes to a similar structure (Li 2 MSiO 4 where M = divalent ions), very few works are reported on TL properties.…”

O2 Loaded Germanosilicate Optical Fibers: Experimental In Situ Investigation and Ab Initio Simulation Study of GLPC Evolution under Irradiation

“…One of the most important defects related to applicative and basic research relevance is the Germanium Lone Pair Center (GLPC [19]) in Ge-doped silica, which is employed to produce one of the most common optical fiber types in telecommunications and sensing applications [20,21]. It is accepted that the GLPC is an electron donor and that its presence affects the sensitivity of the silica to radiation or laser exposure [11,16,22].…”
