Abstract: Abstract Polycrystalline (1-x)[(Na0.5Bi0.5)0.95Ba0.05]0.98La0.02TiO3-xK0.5Na0.5NbO3 systems were prepared using the solid-state reaction technique. Modification of (Na0.5Bi0.5)0.95Ba0.05]0.98La0.02TiO3 ceramic with a proper amount of K0.5Na0.5NbO3 can effectively improve the temperature-stable of dielectric properties. A variation in dielectric constant is… read more here.

Abstract: The Eu-doped K0.5Na0.5NbO3 pellucid ceramics were first prepared via a conventional solid-state reaction, and they exhibited light illumination-induced high-contrast photochromism of both optical transmittance and photoluminescence behaviors. Through thermal treatment, the optical performances could return… read more here.
