X-ray diffraction (XRD) analysis revealed a predominant orthorhombic phase (<em>Pnma</em>) alignment of SrCeO₃ NPs, which is in agreement with the JCPDS card #01-083-1156, with a calculated crystallite size of 35.38 nm, corroborated by the Williamson-Hall (W–H) plot (37.15 nm).

Scanning electron microscopy (SEM) images showcased a coral-like morphology, while energy-dispersive X-ray spectroscopy (EDAX) confirmed the presence of precursor elements. Further, Fourier-transform infrared spectroscopy (FTIR) of the as-prepared SrCeO₃ NPs confirmed the presence of metal-carbonate vibrations within the range of 1600-1200 cm⁻¹, along with metal-oxygen stretching in the range of 900-650 cm⁻¹. Raman spectroscopy exhibited an intense peak at 459.78 cm⁻¹, attributed to Ce–O (metal-oxygen) stretching.

Using the Mach-Zehnder interferometry technique, the unpoled tetragonal phase SBN crystal was confirmed to exhibit a quadratic electro-optic effect, with the coefficient measured to be approximately 10⁻¹⁵ m²/V². The quadratic EO effect was mainly attributed to the high symmetry introduced by the randomly distributed domain structures. However, the poling effect of a high applied voltage can align the dipoles in each microdomain in the same direction, leading to the transition of the crystal from a quadratic EO effect to a linear one. A beam deflection system utilizing the composition gradient and quadratic electro-optic (EO) effect was established. At lower voltages, the deflection angle exhibited a parabolic increase with the applied voltage, while at higher voltages, it decreases due to the poling effect. A maximum deflection angle of 10 mrad was obtained by applying 880 V/mm on an SBN crystal with the dimension of 5.8 mm × 2 mm × 1 mm. A theoretical model that accounts for both the gradient of the intrinsic refractive index and the EO effect was constructed.
