Photometric features and intense blue light emanation of Nd3 doped SrTiO3 based nanophosphor for multi-functional applications

The optimized nanophosphors were used to visualize latent fingerprints through recognizing level I-III ridges by a reduced background hindrance and can be utilized for visualizing latent fingerprints on difficult substrate surfaces with superior sensitivity, high contrast and selectivity. Further, a furthermost possible stochastic process to make unclonable anti-counterfeiting tags using optimized nanophosphor was designed to reduce counterfeit products.
