Abstract (en)
[origin: WO2007042653A1] The inventive rare earth borate is embodied in the form of a liquid phase suspension of substantially monocrystalline particles whose mean size ranges from 100 to 400 nm. Said borate is produced according a method consisting in roasting a rare earth borocarbonate or hydroxyborocarbonate with a temperature which is sufficient for forming a borate and obtaining a product whose specific surface area is equal to or greater than 3 m<SUP>2</SUP>/g and in carrying out the humid grinding of the roasted product. The inventive borate can be used in the form of luminophor, in particular, for producing a luminescent transparent material.
