Luminescent aluminate nanotubes doped with cerium and co-doped with other lanthanide ions for pigments used in optical devices, floor ceramic tiles, paints (10 PT 65BN 3IFD)
A Portuguese public university has developed new luminescent nanomaterials, called luminescent aluminate nanotubes doped with cerium (III) and co-doped with other lanthanide ions, which can be widely applied in raw materials used in optical devices, such as sensors and biomarkers, photoluminiscent floor ceramic tiles, paints, etc.
They are looking for companies who produce inorganic phosphorus and inorganic pigments, in order to realize licensing agreements.

The motivation for the development of this invention was essentially driven by the will to create innovative solutions that facilitate the life of disabled people, producing new products with the property of persistent (light emission longer than 10 hours), in a nano scale.
The present invention provides luminescent aluminate nanotubes doped with cerium (III), and co-doped with other lanthanide ions (Ln is La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, Tm or Lu).
These luminescent nanotubes are obtained by a synthesis process which consists in a thermal treatment of post-annealing from precursor micro- and nano-particles, under temperature range equal or higher than 573 Kelvin, for a minimum time of 30 minutes. These luminescent nanotubes result in light emissions in the visible ultraviolet and infrared regions.
Innovative Aspects:
New material that offers a novel photoluminescent nanostructure nanotube-shaped, having as an advantage a synthesis process that allows a large scale production of nanotubes.
