The present study was carried out to analyze the effect of a green reducing agent and a chemical fuel used in the synthesis of nanoparticles (NPs) on their magnetic, photoluminescence (PL), photocatalytic, and electrochemical behavior. Magnesium ferrite (MgFe2O4) NPs were synthesized via both chemical and green combustion route using glycine (MFG) as a fuel and Syzygiumaromaticum (clove oil) as a reducing agent (MFCL). Both MFG and MFCL NPs exhibited a cubic spinel structure; however, compared to MFG, more planes are pronounced in MFCL NPs. A larger crystallite size was observed in MFCL rather compared to MFG NPs. Transmission electron microscopy analysis supported the Bragg reflections, while X-ray photoelectron spectroscopy confirmed the presence of Mg 1s, Fe 2p, O 1s and C 1s elements. From the Hysteresis loop, magnetic parameters such as saturation magnetization, retentivity, coercivity and squareness ratio were calculated. The PL emission spectra, CIE and CCT values clearly indicate that the sample could serve as a promising blue nanophosphor material for cool display technologies. Additionally, electrochemical and EIS spectral analysis were performed. The MFCL sample displayed a smaller semicircle diameter than MFG, indicating faster charge transfer at the electrode/electrolyte interface for the clove oil derived material. This result was consistent with the photoactivity of indigo dye, where the MFCL samples showed the highest photodegradation efficiency with 90.41% compared to MFG NPs.
