“…Eu 3+ ions are generally preferred as a co-dopant to compensate the insufficient red emission of Dy 3+ ions and to yield white light emission with increased CRI values. Therefore, emission properties and white light generation through Dy 3+ and Eu 3+ co-doping have been extensively studied in different glass systems such as, zinc-aluminoborosilicates [93], calcium-aluminoborates [94], fluoro-aluminoborates [95], zinc-aluminium-sodiumphosphates [96], zinc-phosphates [97], sodium-tellurites [98], calcium-boroaluminates [19,99], and fluoro-borosilicates [100].…”

“…The PL spectra gave six intense emission bands located at 421 nm (5d → 4f transition of Eu 3+ ), 484 nm ( 4 F 9/2 → 6 H 15/2 transition of Dy 3+ ), 575 nm ( 4 F 9/2 → 6 H 13/2 transition of Dy 3+ ), 590 nm ( 5 D 0 → 7 F 1 transition of Eu 3+ ), 616 nm ( 5 D 0 → 7 F 2 transition of Eu 3+ ) and 700 nm ( 5 D 0 → 7 F 4 transition of Eu 3+ ). The typical broad band of Eu 3+ located at 421 nm is due to large spatial expansion of the 5d wave function and lattice vibrations of the surrounding [95]. As given in figure 13(b), luminescence color properties of these samples were characterized via CIE chromaticity diagram.…”

Nowadays, solid-state white light-emitting diodes (wLEDs) have attracted remarkable attention for applications in general lighting, displays and numerous electronical devices due to their eminent efficiency, longer lifetime and higher mechanical durability compared to traditional incandescent and fluorescent lights. In current commercial wLEDs, a combination of Y 3 Al 5 O 12 :Ce 3+ yellow phosphor with blue LED chip and epoxy resin is generally used to generate white light. However, there are some considerable frailties mostly originated from phosphor and resin such as, degradation upon heat, and moisture, inhomogeneous spectral distribution, and poor color rendering capability. Therefore, phosphor embedded glass-ceramics have been developed as a promising way to obtain durable solid-state lighting devices. However, in these methods, there is a greater risk of reactions between the phosphor material and the glass host. At this point, lanthanide-doped luminescent glasses have drawn great attention as a new generation phosphor and/or epoxy free white-light-emitting source owing to their favorable properties including high thermal and chemical stability, high transparency, and easy manufacturing process. This review article aims to comprehensively summarize the recent progress in singly (i.e., Dy 3+ , Eu 2+ ), doubly (i.e.
