<p>The fluorescent material is an oxynitride-silicate, with a cation M and basic formula M (1-c)Si 2O 2N 2:D c, d being doping with bivalent europium. M is Sr alone, or Sr (1 -xy)Ba yCa x, where x + y is up to 0.5 and the oxynitride-silicate is completely or predominantly the high-temperature modification HT.</p> |
