Diffusion-controlled excitation annihilation in Sr2₂CeO₄ crystal
The contribution from interaction between regular optical centers in Sr2₂CeO₄crystal structure to the migration process of electronic excitation energy has been demonstrated. The Sr2₂CeO₄ crystals have been synthesized by the Pechini citrate method. The luminescence decay process has been studied as...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The contribution from interaction between regular optical centers in Sr2₂CeO₄crystal structure to the migration process of electronic excitation energy has been demonstrated. The Sr2₂CeO₄ crystals have been synthesized by the Pechini citrate method. The luminescence decay process has been studied as a function of the laser radiation density. Parameters of excitation mobility have been estimated. It is shown that the migration in strontium- cerium oxide is rather weak; during its lifetime, the excitation migrates over the 4 chain sites in the arrangement of the optical centers. |
