Tailored structures and dielectric traits of holmium ion-doped zinc-sulpho-boro-phosphate glass ceramics

Customized physical and structural features of phosphate-based glass-ceramics: role of Ag nanoparticles and Ho3+ impurities

“…Conversely, in the second case (Figure 7-b), the couplings of electrons with matrix polar phonons cloud (polaron) was weak due to the covalent type of network (known from the field strength) resulting in the observed deceased in the polaron radius and increased in the field strength. Moreover, the increased trend of polaron radius (first series) suggested the enhancement of the conduction mechanism of these glass-ceramics by the polaron hoping [31,36].…”

“…The recorded low value of the binding energy for the peak (1) and high binding energy value for the peak (2) corresponded to the numbers of NBO and BO, respectively [38]. Again, the areas under these two fitted peaks were used to estimate the ratio of the BO to the NBO + BO occurrences [31,38]. The reduction in the BO:NBO + BO value (0.428) for the ZBPHA0.8 (Series I) sample compared to that of the host glass-ceramic (0.487) clearly indicated the significant role of the Ag NPs embedment into the glass-ceramic network, responsible for the generation of more NBO and structural alterations.…”

Spectral and Up conversion Properties of Ho3+ ions doped Zinc Lithium Lead Soda lime Cadmium Phosphate Glasses

“…Rare earth doped glasses have attracted a great deal of attention because of their applications in thermal imaging, fiber amplifiers, laser fusion, optical fibers, photovoltaic solar cells, optical communications, up-conversion lasers and optical data storage [1][2][3][4][5]. Among different glasses, phosphate glasses have unique properties.…”
