Abstract
Abstract The melt-quenching process synthesized gadolinium oxide and fluoride in borophosphate glasses doped with terbium ions (Tb3+). The effect of fluoride compounds and their impacts on physical, optical, and luminescent properties have been investigated. The glasses absorbed near-infrared, visible light, and ultraviolet photons. The bright green emission circa 542 nm via the 5D4 → 7F5 radiative state of Tb3+ originated. Depending on the excitation, there are several sorts of ultraviolet, visible light, and X-ray. The values of decay time are in the order of milliseconds (ms). The Gd3+-Tb3+ energy transfer is vital in green emission under 275 nm excitation. According to the results obtained in this work, the developed glasses can be suitable candidates for green emission medium.
期刊介绍：
Integrated Ferroelectrics provides an international, interdisciplinary forum for electronic engineers and physicists as well as process and systems engineers, ceramicists, and chemists who are involved in research, design, development, manufacturing and utilization of integrated ferroelectric devices. Such devices unite ferroelectric films and semiconductor integrated circuit chips. The result is a new family of electronic devices, which combine the unique nonvolatile memory, pyroelectric, piezoelectric, photorefractive, radiation-hard, acoustic and/or dielectric properties of ferroelectric materials with the dynamic memory, logic and/or amplification properties and miniaturization and low-cost advantages of semiconductor i.c. technology.
