Abstract

Among fluorescent materials used in imaging diagnostics and biomedical fluorescent labels, rare earth nanomaterials are currently studied strongly. This comes mainly from their good optical properties. Rare earth fluorescence nanoparticles have a wide absorption spectrum, strong emission and long lifetime. In this study, we present some research results on synthesis of fluorescent complex nanomaterials of Tb(TTA)₃ -TA: 3-thenoyltrifluoroacetonate. The obtained nanomaterials have a strongly blue emission with a maximum wavelength of 543nm. They have particle sizes varying from a few tens to several hundred nm that depend on the synthetic method. The characteristic properties of materials are also presented in detail.

Keywords

Nano, complex, fluorescence, Tb(TTA)3, rare earth.
