(1-x) (Al0.2La0.8TiO3) + (x) (BiZnFeO3) (x = 0.2–0.8) [ALTBZFO] nanocomposites were synthesized via hydrothermal method. These nanocomposites are significantly adequate for perfect absorber and high charge stowed capacitor applications. The hydrothermal method is mainly a solution reaction involved methodology to control the morphology of the materials, significantly can control the compositions of nanomaterials through multiphase chemical reactions. The X-ray diffraction patterns indicated the phase transformation from tetragonal for x = 0.2 to cubic for x = 0.4–0.8 samples, respectively. The surface morphology showed the existence of nanospheres-like structures. At 1 MHz frequency also, the dielectric constant was increased from 230 to 710 for x = 0.2–0.6 samples, respectively. Interestingly, x = 0.6 nanocomposite exhibited the negative dielectric behavior having the dielectric constant (ε′) ~ − 58.5 and dielectric loss (ε") ~ − 417 at 8 MHz. Similarly, x = 0.6 sample showed ac-electrical conductivity (σac) − 0.159 S/cm at 6 MHz. Hence, these kinds of materials can provide high charge stored capacitors and perfect absorber applications.
