Abstract

The Tb3+ doped tungsten-gadolinium-borate glasses (WGB:Tb) were prepared by the melt-quenching technique with different Tb2O3 concentration (0.0, 0.1, 0.5, 1.0 and 2.0 mol%). Properties of glasses were characterized by such techniques as Archimedes´ method, XRD, absorption spectroscopy, various types of luminescence spectroscopy and decay curves. Glass performs the enhanced compaction with increment of Tb2O3 content. XRD pattern represents the amorphous nature of glass system. Tb3+ in glass absorbs photons in visible light and near infrared region. The strong green emission around 544 nm via 5D47F5 transition of Tb3+ were generated under three types of excitation such as ultraviolet–visible light (photoluminescence), X-ray (radioluminescence) and electron (cathodoluminescence). The Gd3+ - Tb3+ energy transfer plays an important role for strong green emission of glass. The intensity of this luminescence increases with increment of Tb2O3 concentration. All luminescence decay curves represent in the forms of non-single/multi-component exponential functions. The values of all decay time are in the order of millisecond. Moreover, the emission intensity of Tb3+ reduced with temperature increment (thermal quenching) proved by the temperature-dependent luminescence. In this work, the WGB:Tb glass doped with 2.0 mol% of Tb2O3 is a versatile glass. It is suitable and can be developed for using as a photonic materials in the green light source, laser, display/screen, X-ray detector and scanning/transmission electron microscope.
