Pioneering ginger juice extract mediated synthesis of magnesium indate nanoparticles

Magnesium indate nanoparticles were synthesized via a biomediated route using ginger extract as a reducing agent followed by calcination. The Bragg reflections confirm the formation of an orthorhombic crystal structure with space group Imma. This was in turn confirmed through Rietveld refinement. The crystallite size and other structural parameters were calculated. Agglomerated irregularly sized and irregularly shaped nanoparticles were observed. The direct band gap was found to be 3.16 eV. Photoluminescence analysis was performed with excitation at 250 nm. The photoluminescence intensity and CIE values drop in the blue region of the visible spectrum. The correlated color temperature was found to be 2748 K. Further, the powder dusting method was used to collect latent fingerprints on porous and nonporous surfaces. The synthesized magnesium indate results in well-resolved ridge patterns that can be used to identify latent fingerprints with clarity. From all these results, the present synthesized magnesium indate nanoparticles might find application in display technology as a blue nanophosphor material and for latent fingerprint detection in forensic science.
