“…From an overall standpoint, Gd is a good choice for the application of radiation shielding glasses. In recent studies [ 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ], Gd-containing shielding glasses have mainly focused on γ-ray radiation shielding ability, which should be discussed in the following section. Considering that Gd-containing shielding materials tend to release highly hazardous secondary γ-rays while absorbing neutrons, this type of work should be helpful to improve the comprehensive shielding performance of Gd-containing neutron shielding glasses.…”

With the rising demand for nuclear energy, the storage/transportation of radioactive nuclear by-products are critical safety issues for humans and the environment. These by-products are closely related to various nuclear radiations. In particular, neutron radiation requires specific protection by neutron shielding materials due to its high penetrating ability to cause irradiation damage. Herein, a basic overview of neutron shielding is presented. Since gadolinium (Gd) has the largest thermal neutron capture cross-section among various neutron absorbing elements, it is an ideal neutron absorber for shielding applications. In the last two decades, there have been many newly developed Gd-containing (i.e., inorganic nonmetallic-based, polymer-based, and metallic-based) shielding materials developed to attenuate and absorb the incident neutrons. On this basis, we present a comprehensive review of the design, processing methods, microstructure characteristics, mechanical properties, and neutron shielding performance of these materials in each category. Furthermore, current challenges for the development and application of shielding materials are discussed. Finally, the potential research directions are highlighted in this rapidly developing field.

“…In our previous work [ 4 , 5 , 20 ] it was observed that addition of rare-earth ions enhances the radiation shielding property and hence in the present work it is focused to add rare-earth ions with heavy metal oxide such as Bi 2 O 3 . Addition of rare-earth ions such as gadolinium (Gd 2 O 3 ) content in the glass matrix will enhances the radiation shielding ability [ 21 ] and its optical transmittance which is important property for the glasses [ 22 , 23 ]. The rare-earth doped glasses are most importance for the manufacturing of solid-state luminous applications [ 24 ] and shielding gamma-ray and neutron applications [ 25 ].…”

“…[1][2][3] Being good phosphors, borates have attracted attention due to their good thermal stability, [4] environmental friendliness, [5] long durability, [6] etc. Moreover, borate glass has also proved its worth in optical properties because of its chemical resilience, superior transparency, [7] and good rare earth (RE) ion solubility. [8] Chloroborates have a low softening point but they possess high phonon energy.…”

Borochlorate phosphors have shown their worth in modern day lighting over the last few years. Colour tunability of the phosphor is a modern techniques used to obtain white-light-emitting diodes (WLEDs). In the proposed work, Sm 3+ ,Eu 2+ -activated/co-activated Ba 2 AlB 4 O 7 Cl phosphors were investigated for WLED applications as well as display devices. A convectional solid-state diffusion method was used to synthesize the proposed phosphors. X-ray diffraction (XRD) of the proposed phosphors confirmed the crystalline nature of the sample. Morphological studies on the samples were carried out using scanning electron microscopy analysis. A photoluminescence study of the colour tunable phosphor showed the characteristic peak of Sm 3+ together with one broad peak for Eu 2+ ions. Red to blue colour tunability was observed in the proposed phosphor with enhancement of Eu 2+ ions. All these results showed the worth of this sample in WLED applications as well as in display devices.
