New process for encapsulating luminescent aluminates used in materials for self-cleaning hygienic surfaces, biomaterials, etc. (10 PT 65BN 3IGB)
A public Portuguese University has developed a new process for encapsulating luminescent aluminates, which can be used in materials for self-cleaning hygienic surfaces, in the domain of constructive systems, biomedical systems, aquatic or high humidity level systems, antibiotics, vaccines and biomaterials.
They are looking for companies producers of inorganic phosphorus and inorganic pigments in order to establish licensing agreements.

This new process was developed because the research group has identified a problem in terms of hydrolysis of luminescent materials when in contact with water that needed to be solved, in order to be possible to process and/or apply the materials from aqueous suspensions.
As such, this invention presents luminescent aluminates of Beryllium, Magnesium, Calcium, Strontium or Barium doped with Cerium (III) encapsulated with inorganic titanium dioxide (TiO2)nanoshells that present new multifunctionalities, namely, photocatalytic antimicrobial, antibacterial action and water resistance properties.
The encapsulation process of such aluminates involves dissolving the passivating agent, sodium titanate (Na2TiO3) under conditions of controlled pH, so that titania species are adsorbed onto the surface of aluminates through unsaturated bonds of surface atoms.
Innovative Aspects:
The new process is simple, cost effective, and allows protecting photo luminescent materials against hydrolysis reactions. The resulting material offers unique antibacterial, antimicrobial and photo catalytic properties.
The coating with titanium allows other functionalities for the materials, as titanium has photo catalytic effect.
