Tunable luminescence of Ce3+/Mn2+-coactivated Ca2Gd8(SiO4)6O2 through energy transfer and modulation of excitation: potential single-phase white/yellow-emitting phosphors
TL;DR: In this article, a color-tunable emission in CGS:Ce3+/Mn2+-coactivated Ca2Gd8(SiO4)6O2 (CGS) oxyapatite phosphors has been identified and discussed.
Journal ArticleDOI
Color Tuning Luminescence of Ce3+/Mn2+/Tb3+-Triactivated Mg2Y8(SiO4)6O2 via Energy Transfer: Potential Single-Phase White-Light-Emitting Phosphors
TL;DR: In this paper, the dual energy transfer from Ce3+ to Mn2+ in Mg2Y8(SiO4)6O2 (MYS) oxyapatite phosphors has been demonstrated to be a resonant type via a dipole-quadrupole mechanism, and the critical distance calculated by quenching concentration method and spectral overlap method are 10.5 and 9.7 A, respectively.
Journal ArticleDOI
Single-composition trichromatic white-emitting Ca4Y6(SiO4)6O: Ce3+/Mn2+/Tb3+ phosphor: luminescence and energy transfer.
TL;DR: The studied results indicate that the as-prepared CYS: Ce(3+), Mn(2+), Tb(3+) phosphors have good CL intensity and CIE color coordinate stability with a color-tunable emission crossing the whole white light region under low-voltage electron beam excitation.
Journal ArticleDOI

TL;DR: Ce3+ and/or Eu2+ activated Ca8La2(PO4)6O2 (CLPA) blue phosphors have been prepared via a Pechini-type sol-gel process as mentioned in this paper.
Journal ArticleDOI
Rare earth ions doped phosphors for improving efficiencies of solar cells
TL;DR: In this paper, the authors discuss lanthanide doped luminescent materials which can modify the solar spectrum to reduce the spectral losses encountered by PV (photovoltaic) devices and enhance the conversion efficiency.
