Abstract
Great attention has been paid to synthesize novel luminescent hybrid Eu(Thiol)Phen Nanophosphor complex; where (Thiol) = (E)-2-hydroxy-N/-((thiophen-2-yl)methylene)benzohydrazide and (Phen) = 1,10-phenanthroline as co-ligand. Properties like structure, morphology and optical characters were investigated. The results revealed that binary ligand acts as monoanionic tridentate through N-atom, O-atom and S-atom as donor sites. The secondary ligand (Phen) acting as bidentate through two (CN)pyridine groups. TEM image of ternary hybrid Eu(Thiol)Phen phosphor complex was cleared aggregated hybrid morphologies between sheet and rode shapes and their crystal sizes were in nanodomain. A pure red emission of Eu3+ Nanophosphor complex with long lifetime value was obtained, under harmless UVA, UVB and UVC. Optimized photoluminescence (PL) of Nanophosphor complex effectively developed as a novel sensing material for the visualization of latent fingerprints (LFPs) from various forensic relevant materials, including non-porous and porous of multi-color surfaces as well as security ink applications.
