V. Lupei et al., ENERGY-TRANSFER FROM FE3-EARTH IONS IN YAG AND THE PROBLEM OF SENSITIZATION OF LASER-EMISSION( TO RARE), Journal de physique. IV, 4(C4), 1994, pp. 505-508
The static and dynamic measurements of Tm3+ spectra in YAG:Fe:Tm show
that the H-3(4) level is efficiently populated by transfer from Fe3+ i
n tetrahedral sites. The features of the transfer processes, by invest
igation of Tm3+ acceptor luminescence characteristics, are presented
