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.
