Photolumincence study of Sm³⁺containing sodium borosilicate glasses and glass-ceramics

A one-step synthesis of rare-earth phosphate–borosilicate glass composites

“…3 These materials have found uses for many applications, including: as photoluminescence materials; in fuel cells; as bioactive agents; as textiles; as integrated circuits; and as waste forms to sequester high level nuclear waste. [3][4][5][6] High level nuclear waste is a product of the nuclear fuel cycle and consists, in part, of radioactive actinides. [7][8][9] One method proposed to sequester high level waste is to incorporate these elements into a waste form followed by placement in a geological repository.…”

Use of Eggshell Waste as a source of CaO in Sm3+-Doped Na2O-B2O3-CaO-SiO2 Glass Preparation

“…This type of glass has numerous applications especially as optical glasses [1]. This is because such glass types have good rare-earth ion solubility [2].…”

“…Among the rare earth ions, trivalent samarium ions (Sm 3+ ) have attracted a lot of interest especially in the fields of high-density optical storage and luminescent devices [3]. A strong intense emission band of the Sm 3+ ions occurs at about 600 nm due to 4 G5/2 → 6 H7/2 transition, which emits the bright red-orange light under UV and visible-light excitation [2,4].…”
