An efficient near-infrared (NIR) quantum cutting (QC) Tb3+ and Yb3+ co-doped phosphor Sr3Gd(PO4)3 has been synthesized by conventional high temperature solid technique. Upon excitation of Tb3+ with a visible photon at 485 nm, two NIR photons could be emitted by Yb3+ through cooperative energy transfer (CTE) from Tb3+ to two Yb3+ ions. Excitation and emission spectra as well as fluorescence decay measurements have been carried out to examine the occurrence of cooperative energy transfer (CET ) from Tb3+ to Yb3+ ions. The result indicates Tb3+ and Yb3+ co-doped Sr3Gd(PO4)3 is potentially used as down-converter layer in silicon-based solar cell.

Tb3+, Er3+co-doped K2GdZr (PO4)3samples were prepared by solid-state reaction method and their photoluminescence (PL) properties were investigated in ultra-violet (UV) and vacuum ultra-violet (VUV) region. The results indicate that the energy transfers from Er3+to Gd3+and from Gd3+to Tb3+required for occurring of visible quantum cutting through down-conversion are efficient. In this cooperative energy transfer process, Gd3+is used as an intermediate of energy transfer between Er3+and Tb3+. The optimal quantum efficiency (QE) of this co-doped system K2GdZr (PO4)3: Er3+, Tb3+phosphor reached to 110%, suggesting a potential visible quantum cutting phosphor in practical application.

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.
