This paper reports the influence of La 2 O 3 addition on the optical and photon shielding properties of 75P 2 O 5 – (25-x)Ce 2 O 3 –xLa 2 O 3 (where x  = 0, 5, 10, and 15 mol% coded as PCL-A, PCL-B, PCL-C, and PCL-D, respectively). The optical features of the P 2 O 5 −Ce 2 O 3 :La 2 O 3 glass system were studied by determining several parameters such as optical transmission (T) and optical dielectric constant ( ε optical ). Using FLUKA simulations, the photon shielding parameters of the glass samples were estimated and analysed for photon energies in the range 284–2510 keV. The shielding parameters include the self-attenuation coefficients ( C f ), transmission factors, linear attenuation coefficient (LAC), and radiation protection efficiency (RPE). LAC values were enhanced as La 2 O 3 content of the glasses increased. Based on the estimated parameters, the RPE of the glasses follows the sequence: (RPE) PCL-A
