An investigation has been performed into the influence of Sm3+ substitution on the structural, optical, and magnetic characteristics of Co0.5Mn0.5SmxFe2–xO4 (x = 0.0-0.1 and x changes at a step of 0.02) and its prospective use as an effective photocatalyst. The examination also explored the potential use of this composition as a proficient photocatalyst. The structural results verified the production of cubic spinel structures in all compositions. The determination of crystallite size has been done via the Williamson-Hall approach, taking into account the influence of strain variables. The ferrite nanoparticles’ spherical form was identified via transmission electron microscopy (TEM) examination. The Co0.5Mn0.5Fe2O4 sample exhibited a particle size distribution of around 40 nm. The optical band gap, ascertained using UV–vis-diffuse reflectance (DRS) spectra analysis, ranged from 1.38 to 1.43 eV. Vibrating sample magnetometer (VSM) analysis revealed that the produced sample was soft magnetic with moderate magnetization (58.18 emu g−1 - 42.73 emu g−1). Methylene Blue (MB) dye’s photocatalytic degradation (PCD) was used to study the photocatalytic behavior while exposed to sunlight. The Sm-doped Co-Mn nanoferrites synthesized in this study exhibit potential for use as effective active photocatalysts in the degradation of toxic industrial dyes. This application promises to enhance safety in both the environmental and healthcare sectors.

“…These curves are commonly used to determine and comprehend the basic properties of electronic devices, as well as to investigate their behavior inside an electronic circuit. The value of the ideality factor ( N) , obtained from Equation (13), is used to estimate the transport current of the device [ 36 ]:

where q is the electric charge, T is an absolute temperature, K B is the Boltzmann constant, and I s is the saturation current. The I–V characteristics of the doped specimens were measured using a KI/I2 electrolyte.…”

This study investigated the production of Cu2+-doped CoFe2O4 nanoparticles (CFO NPs) using a facile sol−gel technique. The impact of Cu2+ doping on the lattice parameters, morphology, optical properties, and electrical properties of CFO NPs was investigated for applications in electrical devices. The XRD analysis revealed the formation of spinel-phased crystalline structures of the specimens with no impurity phases. The average grain size, lattice constant, cell volume, and porosity were measured in the range of 4.55–7.07 nm, 8.1770–8.1097 Å, 546.7414–533.3525 Å3, and 8.77–6.93%, respectively. The SEM analysis revealed a change in morphology of the specimens with a rise in Cu2+ content. The particles started gaining a defined shape and size with a rise in Cu2+ doping. The Cu0.12Co0.88Fe2O4 NPs revealed clear grain boundaries with the least agglomeration. The energy band gap declined from 3.98 eV to 3.21 eV with a shift in Cu2+ concentration from 0.4 to 0.12. The electrical studies showed that doping a trace amount of Cu2+ improved the electrical properties of the CFO NPs without producing any structural distortions. The conductivity of the Cu2+-doped CFO NPs increased from 6.66 × 10−10 to 5.26 × 10−6 ℧ cm−1 with a rise in Cu2+ concentration. The improved structural and electrical characteristics of the prepared Cu2+-doped CFO NPs made them a suitable candidate for electrical devices, diodes, and sensor technology applications.
