Characterization of luminescent LTCC composite materials for white LED package
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℃ 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: (a)r=13.09, tan(a)<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.
