Luminescence properties of CaAlSiN3:Eu2+ mixed nitrides prepared by carbothermal process

Mixed metal nitride (CaAlSiN3:Eu2+) phosphor was synthesized from an appropriate mixture of CaCN2, CaCO3, AlN, Si3N4, Eu2O3 and C by the carbothermal nitriding method in a N2 gas flow: 1/2 CaCN2 + 1/2(1-2x)CaCO3 + AlN + 1/3Si3N4 + xEu2O3 + C → (Ca1-xEux)AlSiN3 + CO2↑. The resultant phosphor gave an...

Zusammenfassung:Mixed metal nitride (CaAlSiN3:Eu2+) phosphor was synthesized from an appropriate mixture of CaCN2, CaCO3, AlN, Si3N4, Eu2O3 and C by the carbothermal nitriding method in a N2 gas flow: 1/2 CaCN2 + 1/2(1-2x)CaCO3 + AlN + 1/3Si3N4 + xEu2O3 + C → (Ca1-xEux)AlSiN3 + CO2↑. The resultant phosphor gave an intense red emission and good high-temperature durability for LED solid illuminations by optimizing some synthesis conditions.
