    Abstract: There are described luminescent materials based on zinc silicate activated with manganese which are not sensitive to impurities are not susceptible to pulverizing, are temperature stable, and are stable to the customary ceramic glazes. They comprise, consist of (or consist essentially of): 1.5 to 94.8 mole % zinc oxide (ZnO) 1 to 90 mole % Silicon dioxide (SiO2) 0.2 to 1.3 mole % Manganese oxide (MnO) 0.1 to 25 mole % Alkali oxide and/or Alkaline earth oxide and/or Titanium oxide (TiO2) and/or Zirconium oxide (ZrO2) and/or Chromium oxide (Cr2O3) and/or Lead oxide (PbO) 0.1 to 23.8 mole % Sodium oxide (Na2O) 1.3 to 24 mole % Aluminum oxide (Al2O3) and 2.5 to 48 mole % Silicon dioxide (SiO2).
