✦ Synopsis

The quantum efficiency and luminescence properties of double activated terbium aluminum garnet samples were investigated in the present study. A mathematical procedure and PL measurement system are developed for express analysis of quantum efficiency of luminescent materials. The energy-level diagram was proposed to explain the luminescence mechanism. Application of TAG:Ce,Eu with improved CIE and CRI in LED device is demonstrated.

The luminescence properties of doubly activated terbium aluminium garnet samples were investigated in the present study. Commercial Tb 3 Al 5 O 12 :Ce 3+ (TAG:Ce) shows the typical Ce 3+ ion luminescence of the allowed Ce 3+ d-f transition. Eu 3+ co-doping, however, reveals interesting results. In T
