Characterization of Luminescent LTCC Composite Materials for White LED Package

Abstract:

Luminescent low temperature co-fired ceramic (LTCC) was prepared by sintering powders selected from BaO-TiO₂-B₂O₃-SiO₂ system with limited amount of additive (Dy³⁺). It was found that the optimal sintering temperature was 900°C based on the microstructure and the properties of sintering bodies, and then the major phases of the LTCC were Ba₂(TiO)Si₂O₇ and SiO₂. The experimental results indicated that the glass-ceramic possesses good yellow emission under 454nm excitation, excellent dielectric properties: ε_r= 13.09, tanδ<0.001 at 1 MHz. Thus, this material is supposed to be used as the LTCC substrate material for the application in white LED packaging.
