In-depth analysis of the current state of knowledge on lead-telluride glasses and their properties | Original Article

ABSTRACT:

Significant amounts of research on glasses have been focused on complicated glasses like tellurite and phosphotellurite as their principal research topics since the 1960s and 1970s. As is the case with glasses containing tellurium dioxide, well-known glasses also incorporate additional cations as matrix modifiers, as is also the case with glasses containing tellurium dioxide. Numerous researchers have investigated the spectroscopic properties of rare earth ions found in tellurite glasses. The investigation by comparing and contrasting the optical spectra of Pr3+, Nd3+, Eu3+, Ho3+, and Er3+ in Na2OTeO2 glasses with those of the same species in silicate and fluoroberyllate glasses. After making the discoveries that the activator-ligand interaction in tellurite is more covalent than the interaction in fluoroberyllate glass, that tellurite's site symmetry is lower than that of fluoroberyllate glass, and that tellurite's average crystal field at the rare earth site is lower than that of silicate glasses, they came to the conclusion that tellurite is the more advantageous material. The literature review of this study was carried out by screening various global data sets including the web of science, Scopus, PubMed, NIH library and Science Direct. The main aim of this study was to assemble and categorize the synthetic and characteristic properties of lead based telluride glasses.
