摘要：

Transient and persistent spectral holes were burned in the F-7(0)-D-5(0) transition of Eu3+ ions in macromonolithic transparent porous nanocrystalline gamma-Al2O3 produced by sol-gel technology. An unusual temperature dependence of the transient hole width was observed that differs markedly from that in either crystalline or disordered systems. This temperature dependence is explained in terms of Raman processes involving size-resonant vibrations of the nanoparticles comprising the structure. Possible mechanisms of hole burning are suggested.
