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.
