Acetate–citrate gel combustion: a strategy for the synthesis of nanosized lutetium hafnate phosphor powders

Author affiliations

Abstract

The synthesis of rare-earth doped Lu4Hf3O12 phosphor nanopowders was achieved through the combustion of metal–organic acetate–citrate amorphous gels. Their crystalline structure and morphology have been characterized by X-ray diffraction and electron microscopy. Under UV and X-ray excitation a bright luminescence of the Eu3+ and Tb3+ dopant ions has been monitored by photo-luminescence as well as by radio-luminescence measurements. We highlight the role of the formation of nanosized precursor gels as an intermediate stage in the synthesis of high-density rare-earth doped Lu4Hf3O12 luminescent nanopowders.
