Development of a cyan blue-emitting Ba₃La₂(BO₃)₄:Ce³⁺,Tb³⁺ phosphor for use in dental glazing materials: color tunable emission and energy transfer.

ABSTRACT: The Ce³⁺/Tb³⁺ doped Ba₃La₂(BO₃)₄ phosphors were synthesized by a conventional solid state reaction method. The synthesized phosphor samples are a single phase of Ba₃La₂(BO₃)₄ and showed angular-shaped fine grains with average particle size from 5 μm to 10 μm. The Ba₃La₂(BO₃)₄:Ce³⁺ phosphors showed an asymmetric broad blue emission under excitation at 365 nm and the Ba₃La₂(BO₃)₄:Tb³⁺ phosphors exhibited typical green emission assigned to the 4f-4f transition of Tb³⁺ under excitation at 254 nm. Under near-UV (365 nm) excitation, Ba₃La₂(BO
