Luminescence properties of Dy3+ doped and Dy3+/Ce3+co-doped CaO–Al2O3–SiO2–B2O3 glass for LED applications

Improving green emission of Tb3+ ions in BaO‐B2O3‐P2O5 glasses by means of Al3+ ions

“…Furthermore, Al 3 + ions are reported to de‐cluster RE 3+ ions (like Tb 3 + ) in the glass network and facilitate an increase in luminescence efficiency by decreasing luminescence quenching. In fact, earlier studies using molecular dynamics simulations have indicated that co‐doping with Al 3 + is effective in dispersing RE ions in several other glass matrices . According to these studies, Al 3 + ions scatter the RE ions and form Al–O–RE bonds.…”

Recent progress in lanthanide-doped luminescent glasses for solid-state lighting applications—a review

“…The emission color shifted from white to blue with increasing concentration of zCe 3+ (z = 0.06-0.35 mol%) under 374 nm excitation. However, as can be seen in figure 18(b), all the samples are within the white light region under 387 nm excitation [111]. In summary, Dy 3+ /Ce 3+ co-doped glasses can be sufficiently excited by UV light.…”

“…Eventually, white light can be achieved with the appropriate Ce 3+ and Dy 3+ doping concentration or by varying excitation wavelength. The significant amount of research on white light generation through Dy 3+ /Ce 3+ co-doping has been reported in different glass hosts such as, metaphosphate [108], borosilicate [109], zinc-sodium-aluminosilicate [110], and calcium-aluminosilicate [111].…”

“…For example, figure 17(a) illustrates the emission spectra of 0.25Dy 3+ /zCe 3+ (z varies between 0-0.35 mol%) co-doped calcium alumino-borosilicate glass system (CaAlSiB) under 374 nm excitation [111]. The PL emission spectra show three characteristic emission bands centered at 420 nm ( 2 D → 2F 7/2 transition of Ce 3+ ), 485 nm ( 4 F 9/2 → 6 H 15/2 transition of Dy 3+ ), and 577 nm ( 4 F 9/2 → 6 H 13/2 transition of Dy 3+ ).…”

Photoluminescence Enhancement of SiO2‐Coated LaPO4:Eu3+ Inverse Opals by Surface Plasmon Resonance of Ag Nanoparticles

“…Photoluminescence (PL) properties from rare earth ions have attracted much attention for their potential application in the light‐emitting devices, spectral conversion of solar cells, and luminescence sensors . The PL manipulation from rare earth ions is a fundamental problem faced in their applications.…”
