Investigating the Nonlinear Optical Behavior of La1-xCaxCo0.5Mg0.5O3 Perovskites

In this study, we synthesized a series of La...Ca.Co0.5Mg0.5O. perovskites with varying Ca content (x = 0.00, 0.15, 0.45, 0.75) using the citrate method, aiming to explore the relationship between magnesium doping and the nonlinear optical (NLO) behavior of the materials. Structural and optical characterizations were carried out, with a focus on the impact of Mg substitution on the diffraction ring patterns observed during NLO measurements. Our results reveal that increasing Mg content leads to significant changes in the nonlinear optical response, with a notable enhancement in NLO properties as Mg concentration rises. This suggests that the modification of the perovskite structure through Mg doping plays a crucial role in tuning its optical properties. Convection and conduction flow are also discussed in this article. It is shown that the nanofluid becomes dominated by one flow over the other after some time. The findings demonstrate the potential of La...Ca.Co0.5Mg0.5O. perovskites as promising materials for applications in nonlinear optics and photonic devices, where compositional control can be used to optimize performance.
