We report a breakthrough concept for a bulk single crystal as a heavy aluminum perovskite scintillator, where due to bandgap engineering by a balanced Gd admixture in a Lu cation sublattice, the scintillation performance dramatically increases. In an

Ho3+ codoping of YAG:Ce induces an acceleration of Ce3+ decay. This is caused by a non-radiative energy transfer from Ce3+ to Ho3+ which is enabled by a multipolar interaction between the ions. The photoluminescence decay characteristics were examine

In the doubly doped YAG:Ce,Er single crystal we show the effect of the nonradiative energy transfer from the donor (Ce3+) to the acceptor (Er3+) in terms of the Forster-Dexter model. Such an energy transfer process is enabled by the overlap of the do
