“…The presence of broad hump at 2θ around 20°-40° shows that the glass was in amorphous nature. This result was in good agreement with the previous study of X-ray diffraction which shows that no sharp peaks observed from the spectra of erbium zinc tellurite glass system with only presence of a hunch for 2θ around 25°-40° indicating that the prepared samples were fully amorphous [10].…”

A laser cavity was constructed for excitation of erbium doped zinc tellurite glass rods embedded with various concentration of Ag nanoparticles. Central to the system is a Xenon flashlamp for optical pumping, and mirrors to amplify the light waves. The amorphousity of the glass rod was studied by X-ray diffraction and the existence of silver nanoparticles inside the glass was confirmed by high resolution transmission electron microscopy analysis. The photoluminescence properties and differential thermal analysis curve of the samples confirmed the compatibility of the rods as gain medium. The rods were successfully fabricated and incorporated inside the laser cavity. The output of the laser with erbium doped zinc tellurite glass rods embedded with Ag nanoparticles was characterized via spectrum analyser and was found that the spectrum dominated at line 473 nm and 506 nm. The beam profiler was utilized to detect and display the laser beam in 3D.

New tellurite glasses having compositions: 60TeO2-(35-x)ZnO-3Bi2O3-2Na2O-x PbO and 55TeO2-(41-x)ZnO-2Bi2O3-2Na2O-x PbO where x = 0 and 0.5 mol% were fabricated and characterised in order to study the effect of substitution of PbO by ZnO. Density measurement was carried out by applying Archimides principle, that is by using pycnometer. Refractive index measurement was carried out by applying Brewster angle method, at which the intensity change in transversed magnetic light (λ = 632.5 nm) was recorded. From the experiment it can be shown that the glass density increses with the increse of PbO concentration, for the first glasses it change from 5.71 to 5.74 gr/cm3 while for the later it change from 5.85 to 5.87 cm3. Their molar volumes, however, behave inversely. Refractive index change due to this compostional change behave in same manner as density, refractive index increses with the increase of PbO content. Refractive indexes of the first pair are 1.89 and 1.93, respectively, while the later are 1.88 and 1.95, rspetively. Based on these findings, each pairs is a potential candidate for fabricating fiber optic at which the lower index is for cladding material while the higher index for core material.
