ChemInform Abstract: Novel Blue‐Emitting Na x Ca 1‐x Al 2‐x Si 2+x O 8 :Eu 2+ (x = 0.34) Phosphor with High Luminescent Efficiency for UV‐Pumped Light‐Emitting Diodes

Abstract The new blue‐emitting phosphor Na 0.34 Ca 0.66 Al 1.66 Si 2.34 O 8 :Eu 2+ (I) is synthesized by addition of an EtOH solution of Si(OEt) 4 to an aqueous solution of NaNO 3 , EuCl 2 , Ca(NO 3 ) 2 , and Al(NO 3 ) 3 followed by solvent evaporation (120 °C, 24 h) and firing of the dry powder in...
