Multi lanthanide doped fluoride phosphors for VUV excitation

摘要

In conclusion the enhancement of Gd~(3+) 311 nm emission (~6P_J- ~8S_(7/2)) in YF_3 host with the addition of Pr was observed. The energy transfer from this level to other 4f levels in suitable activators such as Eu and Tb may produce efficient VUV phosphors. A survey of suitable activators for energy transfer from ~6P_J of Gd~(3+) is now in progress.
