摘要
Phosphate particulates of at least one rare-earth metal (Ln), with Ln being at least one rare-earth metal selected from among cerium and terbium and optionally lanthanum are in the form of a suspension in a liquid phase of primary isotropic monocrystalline monazite particles having an average size of at least 25 nm and agglomerated into secondary particles having an average size of at most 400 nm; useful luminophores are produced from such phosphate particulates.
