A series of trivalent europium (Eu 3+ ) ions doped zinc sodium strontium activated bismuth phosphate (P 2 O 5 -Bi 2 O 3 -Na 2 CO 3 -SrCO 3 -ZnF 2 -Eu 2 O 3 ) glasses of different dopant ion compositions have been prepared by conventional melt quenching technique. Physical and optical parameters of the prepared glasses such as density (ρ), molecular weight (M i ), molar volume (V M ), rare-earth ion concentration (N RE ), polaron radius (r p ), inter nuclear distance (r i ) field strength (F), oxygen to phosphorus (O/P) ratio, refractive index (n), dielectric constant (ϵ), reflection losses (R), molar refractivity (R M ), electron polarizability (α M ), susceptibility (χ) oxygen packing density (OPD), metallization (M) and reflection factor (P) have been evaluated using the standard formulae. The amorphous/glassy nature was confirmed by the XRD pattern showing the broad hump cantered at 2θ=28° Surface morphological studies have been carried out using SEM analysis and EDS spectra reveal the successful incorporation of Eu 3+  ions into the host matrix. Structural information was obtained from FT-IR spectra, recorded in 4000-400 cm −1  spectral region which consists of symmetrical, asymmetrical stretching and bending P=O, P-O-P, O-P-O and P-O-H vibrations along with OH -  groups. Furthermore, all the prepared glasses were subjected to study for their optical and luminescence properties in detailed.
