Improved near-infrared up-conversion emission of YAG:Yb,Tm phosphor substituted by Gallium and Indium

Gallium–Indium co-substituted yttrium aluminum garnet (YAG:Yb,Tm) phosphors were synthesized by co-precipitation method. It can be seen that gallium and indium ions co-substitution didn’t change the phase of YAG. The upconversion luminescence (UCL) properties of the Gallium–Indium co-substituted (YA...

Description
Summary:Gallium–Indium co-substituted yttrium aluminum garnet (YAG:Yb,Tm) phosphors were synthesized by co-precipitation method. It can be seen that gallium and indium ions co-substitution didn’t change the phase of YAG. The upconversion luminescence (UCL) properties of the Gallium–Indium co-substituted (YAG:Yb,Tm) samples were measured under 980 nm excitation. The effects of different In 3+ concentration on the luminescence properties of Gallium–Indium co-substituted (YAG:Yb,Tm) were also investigated. The fluorescence-lifetime investigation shows that the substitution of Ga 3+ and In 3+ has a significant influence on energy transfer between Yb 3+ and Tm 3+ in the YAG samples.
