New europium-, praseodymium- and manganese-doped barium magnesium silicate, aluminosilicate, gallosilicate or borosilicate useful as a luminophore, e.g. in light-converting materials

摘要

Europium-, praseodymium- and manganese-doped barium magnesium silicate, aluminosilicate, gallosilicate or borosilicate (I), is new. Europium-, praseodymium- and manganese-doped barium magnesium silicate, aluminosilicate, gallosilicate or borosilicate (I) of formula (1) is new: Ba3(1-x-y)Eu3xPr3yMg1-zMnzSi2(1-3v/2M3vO8 (1). M = Al, Ga or B; x, z = 0-0.3 but not zero; y = 0-0.1 but not zero; v = 0-0.1. Independent claims are also included for: (1) light-converting material comprising (I) and a matrix; (2) greenhouse lining comprising the light-converting material; (3) photoluminescent device comprising (I); and (4) plastic, paint, glass or cosmetic product containing (I) as an agent for protection against UV radiation.
