An economic low-temperature self-ignition solution combustion method was used to synthesize 1–11 mol% chromium ion (Cr3+) doped MgAl2O4 nanoparticles (NPs). The structural, morphological and energy gap variations due to the influence of Cr3+ on the host matrix were evidenced by powder X-ray diffract...
