A near Infrared (NIR) quantum cutting (QC) Sr3AlO4F:Tb3+,Yb3+phosphor was synthesized by the conventional high temperature solid-state reaction. The luminescence spectra both in visible (VIS) and NIR regions and decay lifetime curves of Tb3+have been measured to prove energy transfer (ET) from Tb3+to Yb3+. Quantum efficiency (QE) related to Yb3+concentration was calculated and the highest QE was found to be 135% hen Yb3+doped concentration at 20%. The present Tb3+and Yb3+co-doped Sr3AlO4F phosphor may be a promising candidate to modify the spectral of the solar light.

Novel warm-white emitting phosphors CaIn2O4:Dy3+ co-doped with Gd3+, Zn2+, or Al3+ ions were prepared by solid state reaction. In this paper, a strategy of co-doping with different ions was used with the aim of affecting the luminescence properties of CaIn2O4:0.6%Dy3+ under NUV excitation. The luminescence intensities of CaIn2O4:0.6%Dy3+ were enhanced by 0.2% Gd3+ or 0.2% Zn2+ ions co-doping under 367 nm excitation, but lowered by co-doping with 0.2% Al3+ ions. Furthermore, the chromaticity coordinates of CaIn2O4:0.6%Dy3+ can be tuned from the cold-white region to warmwhite region with Gd3+ or Zn2+ ions co-doping. These findings show that CaIn2O4:0.6%Dy3+, 0.2% Gd3+, and CaIn2O4:0.6%Dy3+,0.2% Zn2+ have potential application value as new warm-white LED phosphors.
