Quantum cutting downconversion in Tb3+,Yb3+ codoped Sr3AlO4F phosphor

摘要：

　　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.
