Ceramic Samples

(1-x)BaTiO3-xCaCu3Ti4O12 ceramic powders (where x = 0, 0.02, 0.04, 0.06, 0.08 and 1) were synthesized by solid state reaction method and sintered at up to 1250?C. Phase formation, elemental composition and microstructure of all the samples were investigated by XRD, EDX and FESEM, respectively. The BT-CCTO ceramic samples corresponding to x = 0.04 content showed the best dielectric properties. The improvement of dielectric properties was attributed to the presence of oxygen vacancies. Ferroelectricity was retained for CCTO content up to x = 0.06.

Silicate Phosphors

Zinc silicate-based (Zn2SiO4:Eu3+) long afterglow phosphors were produced by solid state reaction method. The effects of borax and Eu2O3 additive on the properties of fabricated products have been studied. The results show that, there is not much difference in phase compositions within the borax additive amount; however, their SEM morphologies are different. Borax additive can increase the grain size of the product. Some sintering phenomena could be observed in the sample with Eu2O3 addition. The fluorescence spectroscopy results indicate that, the emission peak of the sample with Eu3+ additive located at 612nm, which may be a good candidate for red phosphor applications. The luminescent mechanism of Zn2SiO4:Eu3+ is also discussed.
