New design of highly sensitive and selective MoO3:Eu3+ micro-rods: Probing of latent fingerprints visualization and anti-counterfeiting applications

Red colour light emitting Eu3+ ions activated MoO3 nanophosphors (NPs) were prepared through an ultrasound assisted sonochemical method using Aloe Vera (A.V.) gel as a bio-surfactant. Properties like crystal structure, morphology, optical band gap, luminescent properties, radiative parameters of prepared samples and their use in latent fingerprint (LFPs) visualization were reported. Powder X-ray diffraction results revealed the single...
