This work will present the effect of calcium fluoride in lithium phosphate oxide glass. The glass compositions based on 69 P2O5–20Li2O–10Al2O3–1Sm2O3 and 59 P2O5–20Li2O–10Al2O3–10CaF2–1Sm2O3 are prepared by melting and quenched technique. The physical, structural, optical, and spectroscopic properties have been investigated to determine the performance of calcium fluoride on lithium phosphate oxide glass. The density and refractive index of glass without CaF2 have higher values compared to glass added with CaF2. The FTIR spectrum showed the reduction of the O-H group in a glass added with CaF2. The absorption band of Sm3+ ions start from 6H5/2 as the ground state in the UV-Vis-NIR region. The spectroscopic properties of the glasses have been obtained by using J-O analysis. © 2022 Taylor & Francis Group, LLC.
