PROBLEM TO BE SOLVED: To provide a blue/green to UV radiation up-converting inorganic material with increased efficiency, and a process for the production of that material.SOLUTION: The invention provides a silicate-based lanthanide ion doped material for converting electromagnetic radiation energy of a longer wavelength below 530 nm to electromagnetic radiation energy of shorter wavelengths in the range of 220 to 425 nm. The silicate-based material is a crystalline silicate material doped with lanthanide ions selected from praseodymium, gadolinium, erbium and neodymium. For co-doping, at least two of the lanthanide ions are used. In particular, the silicate-based material is obtainable from a blend comprising salts and an organic solvent by specific calcination processes and tribological impacts to adjust particle size and to increase the crystallinity of the particles. The silicate-based material can be used to inactivate microorganisms or cells covering a surface comprising the silicate-based material under exposure to electromagnetic radiation energy of a longer wavelength below 500 nm.SELECTED DRAWING: Figure 1a
