Fluorescent materials

摘要

Fluorescent materials (M) with a matrix based on silicic acid (hetero)polycondensates (A) and / or organic polymers (B), contg. Pr<3+> ions and opt. other additives. The Pr ions are complexed with cpd(s). (C) contg. electron-pair donor gp(s). and no oxygen atoms, the mole ratio of (Pr ions):(C) = (1:4) - (1:50), and the content of Pr ions in material (M) is 1 - 50 wt. %. Also claimed is a process for the prodn. of materials (M).
