摘要：

La2FeCrO6 nanoparticles were prepared using sol-gel method and their linear and non-linear optical properties were investigated. Optical transmittance and absorption were measured for wavelengths between 200 and 1000 nm using UV–visible analysis at room temperature. The results demonstrated the potential use of La2FeCrO6 in optoelectronics applications due to its interesting optical properties. Transmittance and absorption, as well as absorption coefficients, band gap (Eg), Urbach energy (Eu), refractive coefficients, optical conductivity, and dielectric function were examined. According to the analysis, the band gap energy was determined to be 3.501 eV using the Tauc method, while the Urbach energy value was 0.324 eV. Non-linear sensitivities of the first and third order were also calculated, along with linear and non-linear refractive constants. The results lead to the conclusion that La2FeCrO6 represents a promising material for applications in the field of optical electronics, taking into consideration its optical properties, whether linear or non-linear. © 2024
