“…The obtained values of the glass transition temperature , onset crystallization temperature , and thermal stability ∆ that evaluated via the temperature gap between and ( − ) [13] are shown in concentration implies Er 3+ enrich the glass forming ability. The thermal stability of the glass is an important factor in photonic devices, in which high values of thermal stability are desirable.…”

“…The high intense band located at 649 cm -1 is attributed to the symmetric stretching modes (P-O-P)s linkages of Q 1 [11, 13,21] . The 649 cm -1 band is the highest band and hence it is crossponding to the phonon energy.…”

“…On the other hand, inlaying the phosphate network with ZnO improves the optical and electronic properties of phosphate glass [11][12] . Fluoride host materials have a high quantum yield of luminescence due to ionic bonds and low phonon energy of fluoride [13][14] . Heavy metals rich glass have a combination of desirable optical, mechanical, and thermal properties of its constituents.…”

Developed P2O5-ZnO-PbO-WO3-NaF glasses containing Er 3+ ions were prepared by the melt/casting procedures. X-ray diffraction patterns confirmed the amorphicity of the prepared materials. The density and Fourier Transform Infrared FTIR spectroscopy showed that Er 3+ ions play a modifier role and the studied glasses have low phonon energy. The observed decrease in the measured glass transition temperature indicates that the decrease in the bonding strength of the studied glass structure. The studied glass has a high thermal stability. Vickers microhardness results showed the weakening of the glass network. Measured UV-Vis absorption spectra exhibited several bands in the ultraviolet and visible regions. The studied glass has a high refractive index.The metallization criterion showed that the studied glasses have an insulating behavior. The metallization criterion values of the present glasses are in the range of nonlinear optical materials.Under 320 nm excitation wavelength, the studied glass generates three blue bands at 446, 457, and 473 nm. The CIE-1931 chromaticity diagram coordinates confirmed the blue emission of the prepared glass. According to the obtained results, the produced glasses have a high potential for using as efficient luminescence materials for photonic devices in the blue region.
