Various compositions of Y(Ta,Nb)O4:Eu3 ,Tb3 with different Nb and activator concen- trations have been investigated under UV and VUV excitation. Some compounds with very strong emission under VUV excitation were found. Such phosphors could be proposed as very good emissive materials for Displays and Lightings.
