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

초록

In this study, highly Eu3+-doped (up to 5 mol%) 10ZnO-40Bi(2)O(3)-50B(2)O(3) glasses were prepared by melt quench process. The excitation and emission results of the prepared glasses were recorded in the visible region. The Judd-Ofelt 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 Z-scan 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 Z(eff) results, 10ZnO-40Bi(2)O(3)-45B(2)O(3)-5Eu(2)O(3) exhibited good attenuation properties among the fabricated samples.
