Nowadays, energy-related research is the main concern of researchers to find solutions to problems related to storage, such as thermal stability, and improve the efficiency and generation of energy in terms of energy correlation with the growth of the global economy. We successfully synthesized Nano-compositions based on (1 − x)BaCa0.05Ti0.95O3–(x)SrZn0.5Ti0.5O3 (x = 0.12, 0.14, 0.16, and 0.18) powders. Then, we made an optical ceramic device, such as a multilayer ceramic capacitor (MLCC), using the laser technique and electrodes from gold (Au) deposited on both sides of the coating layers using the sputtering technique. The obtained deposited film phase was investigated based on an X-ray diffractometer, which confirmed the formation of the tetragonal phase for the prepared specimens. The field emission scanning electron microscope test revealed that the increasing concentration of SrZnTiO3 (SZT) dopant in BaCaTiO3 (BCT) samples has improved the density of the composition. Further, electrical properties were improved by enhancement of dielectric constant when increased SZT quantity in the BCT system, as a result of the position of Zn2+at the Sr2+ site in (SZT) dopant would be much more off-center, and the related dipole moments would also be big compared to that of Ca2+ in (BCT) composition. Furthermore, these composites showed thermal stability of dielectric constants and low-loss tangents. In addition, the optical characteristics of the samples investigated by UV–Vis are given in this article.
