Abstract:
The sol-gel technique was applied to the preparation of Eu 3+ ion–doped films, which showed persistent spectral hole burning. A gel film of ∼3500-nm thickness was prepared by dip-coating of the solution synthesized from Si(OC 2 H 5 ) 4 , CH 3 Si(OC 2 H 5 ) 3 , Eu(NO 3 ) 3 · 6H 2 O, and hydropropyl-cellulose. The spectral hole was burned in the 7 F 0 → 5 D 0 transition band of the Eu 3+ ions at 7 K, the depth of which was 24% of the total fluorescence intensity and decreased as the heat-treatment temperature of film increased. It was found that the hole was thermally filled and erased above ∼170 K; the temperature at which the hole was erased was lower for the film heated at high temperature.
