The popularity of inorganic glasses is growing due to their wide range of applications. Therefore, this study focuses on creating a new type of zinc phosphate glasses (ZnP) that contain Eu
3+ ions by using the melt-quenching method. The glasses were made in the following composition: (60-x)P2 O5 -20ZnO-10SrO-10LiF-xEu2 O3 , with x ranging from 0.1 to 2.0%. The XRD profiles of the fabricated glasses revealed their amorphous nature, and the photoluminescence spectra of the prepared glasses displayed five distinct emission bands at an excitation wavelength of 394 nm. Judd-Ofelt (JO) parameters were calculated from the photoluminescence spectra and showed a trend Ω2 > Ω4 . The radiative total transition probabilities (AT ), stimulated emission cross-sections (σ), and quantum efficiencies (η) were also calculated. The5 D0 →7 F2 transition at 612 nm exhibits high intensity. The characteristic color emission of the ZnP glasses was determined by means of the Commission International de l'éclairage (CIE) 1931 chromaticity coordinates (x, y) and lies in the red region. These glasses exhibited strong red luminescence. Zinc phosphate glasses (ZnP) doped with Eu3+ ions have potential applications as red lighting components. [ABSTRACT FROM AUTHOR]- Published
