Control of energy storage of Lu₂SiO₅:Ce³⁺ nanocrystals by co-activation
LSO:Ce, LSO:Ce₁Dy and LSO:Ce₁Yb nanocrystals were synthesized by the sol-gel method. It has been found that the co-activation with Yb³⁺ and Dy³⁺ ions allows the energy storage in a LSO:Ce crystals to be modified and the thermoluminescence and afterglow effects to be controlled. The effect observed i...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | LSO:Ce, LSO:Ce₁Dy and LSO:Ce₁Yb nanocrystals were synthesized by the sol-gel method. It has been found that the co-activation with Yb³⁺ and Dy³⁺ ions allows the energy storage in a LSO:Ce crystals to be modified and the thermoluminescence and afterglow effects to be controlled. The effect observed is due to electron properties of the co-dopant ion (donor or acceptor) causing the trap charge exchange in LSO crystal.
