In this paper, we synthesized series of Eu 2+ activated CaO ceramic powders by conventional solid state reaction. Using NH 4 Cl as a reducing additives, the Eu 3+ has been successfully reduced to Eu 2+ . An intense blue emission peaked at 460 nm from

Near-infrared downconversion phenomenon has been demonstrated in Lu2O3: Tm3+/Yb3+ phosphor upon direct excitation of Tm3+:1G4 level at 463 nm. The efficient energy transfer from Tm3+: 1G4 → Yb: 2F5/2 has been elucidated by the excitation spectra, t

Phosphor‐converted light‐emitting diodes (pc‐LEDs) with broadband near‐infrared (NIR) emission have emerged as compact light sources for portable NIR spectroscopy. However, the associated broadband NIR phosphors suffer from low quantum effici
