We performed characterization of the optical properties of the Cr3+ ion in YAGG via steady-state and time-resolved photoluminescence, cathodoluminescence and thermal quenching experiments. The influence of the preparation method is checked, as we compare the luminescent properties of YAGG:Cr3+ synthesized via solid state synthesis and wet-chemical methods such as coprecipitation. The latter allows for more rigorous control of the grain size and the distribution of Cr-dopants in the host.
