Photoluminescence, nonlinear optical and gamma radiation shielding properties of high concentration of Eu2O3 doped heavy metal borate glasses

In this study, highly Eu3+doped (up to 5 mol%) 10ZnO40Bi2O350B2O3 glasses were prepared by melt quench process. The excitation and emission results of the prepared glasses were recorded in the visible region. The JuddOfelt intensity and CIE chromaticity parameters of the glasses were calculated and discussed. The nonlinear optical properties of glasses were studied at a pumping wavelength of 532 nm under a nanosecond regime utilizing the sensitive Zscan technique. We investigated the linear attenuation coefficient (LAC) for the prepared glasses for energies ranging from 0.296 to 1.458 MeV. According to the Zeff results, 10ZnO40Bi2O345B2O35Eu2O3 exhibited good attenuation properties among the fabricated samples.
