Abstract
- Doubly doped LaF<subscript>3</subscript>:Er, Nd scintillation crystals were grown by modified micropulling-down method. The Er codoping was chosen to enhance the energy transfer from the host lattice to the Nd<superscript>3+</superscript> luminescence center via the 5d-levels of Er<superscript>3+</superscript>, which can be enabled by the overlap of Er<superscript>3+</superscript> 5d-4f emission spectrum with the Nd<superscript>3+</superscript> 4f-5d absorption. However, no relevant energy transfer was found by photo- and radioluminescence spectra measurements. The reasons of no significant positive effect of Er codoping are discussed. [ABSTRACT FROM AUTHOR]
