Abstract

Selectively excited Cr³⁺ and Nd³⁺ emission spectra and excitation spectra of YAlO₃:Nd, Cr crystals are presented. Up to eight Nd³⁺ and three Cr³⁺ multisites are observed in these crystals. Cr³⁺→Nd³⁺ energy transfer is observed between various multisites starting from ²E Cr³⁺ energy levels. Cr³⁺ donor decay can be adequately fitted according to the standard Inokuti-Hirayama theory but a spatial correlation between Cr³⁺ donors and Nd³⁺ acceptors results in a better fit of Cr³⁺ fluorescence decay curves.
