We consider the energy transfer between different sites in chromium-thulium-doped yttrium aluminum garnet. Subtle changes in the spectroscopic levels allow us to selectively excite different sites, with considerably different dynamic and spectral beh

Spectroscopy of Pr-doped YA1O 3 (YAP) has been investigated under synchrotron radiation and laser excitations. Fast UV fluorescence was shown to be due to allowed d–f transitions of Pr 3+ . Light yield of Pr-doped YAP has been measured in compariso
