摘要

In this work, we carry out a comparative investigation of properties for 17Li₂O:17Gd2O3:(66-x) P2O5:xCeF3 (GdO-CeF), and 17Li2O:17GdF3:(66-x)P2O5:xCeF3 (GdF-CeF) glasses, where x = 0.00, 0.05, 0.1, 0.5, 1.0, and 2.0 in mol%. The density of the present glasses shows an increasing trend with the increasing concentration of the CeF3, while the molar volume decreases. It is recorded that the GdO-CeF glasses have a higher density than the GdF-CeF glasses. The luminescence intensity increases as the CeF3 concentration increases up to 1 mol% and then starts dropping. The decreasing trend of the luminescence intensity is due to the cross-relaxation process. It is also noted that GdF-CeF glasses show comparatively higher emission intensity than GdO-CeF glasses. The enhancement of the luminescence intensity is attributed to the lower phonon energy and lower concentration of the OH group. The FTIR spectroscopy confirms that GdF-CeF glasses have lower OH content because the band attributed to the OH group shows lower intensity as compared to the GdO-CeF glasses. Moreover, the integral scintillation efficiency of the present glasses was calculated and compared to the BGO crystal. From the results, it is found that the GdF-CeF glass shows higher efficiency compared to GdF-CeF glass. The impressive luminescence performance of Ce ions in the present glasses highlights these glasses as a promising candidate for next-generation scintillation applications.
