β¦ Synopsis
The mechanism of energy transfer between Mn*++ Nd3* _ III barium borate emission intensities and lifetimes of Mn*+ glass has been investigated. The change in (donor) due to the presence of Nd3+ (acceptor) are observed. it has been concluded that the mechanism of energy transfer involves a nonradiative resonance process. The electrostatic multipIe interaction responsible for the transfer is dipole-dipole in nature.

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
Lead zinc gallium fluoride glass containing 2 mole% TmFS is shown to luminesce from 'Is (35200 cm-'), 'D, (28000), 'G, (2 1500) and 'Hq ( 12800) to several lower J levels. When the 24 mole% ZnF, is replaced by MnF, in the absence of thulium, the (broad band) quartet-to-sextet (ground state) emission
