X-ray diffraction (XRD) confirmed that the prepared samples had cubic crystal structures. No secondary phases were detected due to Gd³⁺ doping. Estimated average grain sizes are of the order of 17, 8, and 6 nm for pure and Gd-substituted MgAl₂O₄ spinel, respectively. X-ray photoelectron spectroscopy (XPS) revealed the presence of Mg, Al, and O, as well as Mg, Al, Gd, and O, for both pure and substituted MgAl₂O₄ samples. Transmission electron microscopy (TEM) analysis revealed that the prepared spinels are nanoscale, and energy-dispersive spectroscopy (EDX) analysis confirms the high purity of the samples prepared. Selected area electron diffraction (SAED) patterns indicated a highly crystalline structure. Optical properties show that the optical energy gap (Eg) increases with the substitution of MgAl₂O₄ spinel by Gd. The photocatalytic activity of pure and doped MgAl₂O₄ nanoparticles was then tested for the photocatalytic degradation of methylene orange (MO) dye. The results indicate that Gd-substituted MgAl₂O₄ spinels exhibit the highest photocatalytic activity and a notable 71% efficiency in dye degradation within 30 minutes under UV irradiation compared to 3% for unsubstituted MgAl₂O₄. The recyclability test showed that MgAl₂O₄ is highly stable. After four cycles, its degradation performance decreased by 6%, from 71% in the first cycle to approximately 65%.

Attention is given to transition-metal, noble-metal, and rare-earth dopants and their influence on crystallographic structure, lattice strain, grain growth, oxygen vacancy formation, and band structure modification. Key sol–gel parameters, including precursor chemistry, chelating agents, hydrolysis and condensation kinetics, pH control, aging conditions, dopant concentration, and calcination temperature, are systematically examined to elucidate their role in dopant dispersion, phase purity, and nanoparticle morphology. The interplay between synthesis conditions and functional performance is critically discussed, highlighting band-gap engineering, charge carrier dynamics, magnetic ordering, and surface reactivity. The review further correlates structure–property relationships with multifunctional applications, including photocatalysis, gas sensing, optoelectronic devices, energy conversion systems, antimicrobial coatings, and biomedical technologies.

Based on the DTA-TGA stability analysis, 370 °C has been used as the optimum calcination temperature for further analysis.
