摘要：

Nd3+ doped phosphate, tellurite, ED-2 and germanate glasses were excited by a laser into different parts of the 4I 9 2 → 4G 5 2 inhomogeneously broadened band. It was found that the germanate glass exhibited wavelength-dependent decay times even at room temperature. It is concluded that the diffusion of energy in the germanate glass is slow because a large energy mismatch between different sites decreases the probability of energy diffusion between them. © 1979.
