✦ Synopsis
Energy transfer rates between Nd(II1) and Yb(II1) in glasses of the basic composition 36 PbFz:24 ZnFz:35 CaFs:2 AlF3:3 YF3:4 LaFs were calculated from donor decay curves, and applied for construction of acceptor luminescence curves. The transfer rates are time dependent and the energy loss by Nd(II1) is quantitatively transferred to Yb(III).
