Effects of thermal annealing on spectroscopic properties of Eu{sup 3+} in Sr{sub 1-X}B{sub x}Nb{sub 2}O{sub 6} films.
Thermal annealing influence on properties of strontium-barium niobate (SBN) films doped with Eu{sup 3+} has been studied using laser spectroscopic methods. The Stark splittings of the {sup 5}D{sub 1} state and all the {sup 7}F{sub J} states are well resolved only in the spectra from the annealed films, whereas the spectra of Eu{sup 3+} in the as-deposited film is similar to that in amorphous phases. Non-resonant fluorescence line narrowing (FLN) is observed only for the annealed film, which indicates a correlation between the energy levels of Eu{sup 3+} in inhomogeneous line broadening. Annealing-induced crystallization of the as-deposited film also increases the {sup 5}D{sub 0} fluorescence lifetime and allows hyperfine spectral hole burning.
