Abstract

Abstract : CaGd2 ZnO5 :Eu 3+ fluorescent nanostructures provide three levels of identification with high-quality imaging on various hydrophilic and hydrophobic substrates. Abstract : Nanostructured inorganic materials are potential building blocks for advanced materials and devices with desired functions. Latent fingerprint technology requires cost-effective and high-quality luminescent nanomaterials to identify an individual with sufficient information. We report the synthesis and growth mechanism of novel nanostructured CaGd2 ZnO3 (CO3 )2 ·H2 O and CaGd2 ZnO5 materials through a urea- and EDTA-mediated hydrothermal process. The conversion from the carbonate to the oxide form is explained using physicochemical measurements. Furthermore, when doped with Eu 3+ ions, CaGd2 ZnO5 nanostructures exhibit superior luminescent properties to replace conventional red phosphors for latent fingerprint technology. In contrast to previously reported individual fluorescent nanoparticles, CaGd2 ZnO5 :5Eu 3+ nanostructures provide three levels of identification with high-quality imaging on various hydrophilic and hydrophobic substrates. These properties demonstrate that CaGd2 ZnO5 :Eu 3+ nanorod bundles are a promising luminescent material for solid-state lighting and latent fingerprint technologies.
