摘要:
Exemplary embodiments of the present invention disclose inorganic luminescent substances with Eu2+-doped silicate luminophores, in which solid solutions in the form of mixed phases between alkaline earth metal oxyorthosilicates and rare earth metal oxyorthosilicates are used as base lattices for the Eu2+ activation leading to the luminescence. These luminophores are described by the general formula (1-x) MII3SiO5.xSE2SiO5:Eu, in which MII preferably represents strontium ion or another alkaline earth metal ion, or another divalent metal ion selected from the group consisting of the magnesium, calcium, barium, copper, zinc, and manganese. These ions may be used in addition to strontium and also as mixtures with one another.
