  • Water-based curable composition for production of coatings comprising phosphors
    Publication number: 20220325176
    Abstract: A water-based curable composition, for production of coatings having an antimicrobial property, contains at least one film-forming polymer, optionally at least one additive and/or at least one curing agent, and at least one up-conversion phosphor of the general formula (I): A1-x-y-zB*yB2SiO4:Ln1x,Ln2z. In the general formula (I), x=0.0001-0.0500; z=0.0000 or z=0.0001 to 0.3000 with the proviso that: y=x+z; A is selected from Mg, Ca, Sr and Ba; B is selected from Li, Na, K. Rb and Cs; B* is selected from Li, Na and K; and preferably B and B* are not the same. Additionally, Ln1 is selected from praseodymium (Pr), erbium (Er), and neodymium (Nd); and Ln2 is gadolinium (Gd). The phosphor, as a result of an aftertreatment, includes at least one material which has a band gap of greater than 6.0 electronvolts (eV) and is hydrolysis-stable.

  • Composition for production of coatings comprising improved phosphors
    Publication number: 20220325177
    Abstract: A curable composition for production of coatings having an antimicrobial property, contains at least one film-forming polymer, optionally at least one additive and/or at least one curing agent, and at least one up-conversion phosphor of the general formula (I): A1-x-y-zB*yB2SiO4:Ln1x,Ln2z. In the general formula (I), x=0.0001-0.0500; z=0.0000 or z=0.0001 to 0.3000 with the proviso that: y=x+z; A is selected from Mg, Ca, Sr and Ba; B is selected from Li, Na, K, Rb and Cs; B* is selected from Li, Na and K; and preferably B and B* are not the same. Additionally, Ln1 is selected from praseodymium (Pr), erbium (Er), and neodymium (Nd); and Ln2 is gadolinium (Gd). The phosphor has been prepared using at least one halogen-containing flux.
